TPS7A1633DGNT 개요
An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage. LDOs belong to the linear regulator family, which is a sub-category of voltage regulators within power management ICs. Unlike switching regulators, LDOs have no switching noise, making them ideal for noise-sensitive analog and RF rails, but they dissipate (VIN − VOUT) × IOUT as heat. The TPS7A16 family extends the LDO hypernym into the wide-input, ultra-low-IQ segment where switching regulators become impractical.
Key features include 60 mV typical dropout at 20 mA, 2% output accuracy, and an integrated open-drain active-high power-good (PG) output with user-programmable delay. The CMOS-compatible enable pin supports sub-µA shutdown, while the PowerPAD EP reduces θJA to enable continuous 100 mA output without external heatsinking at moderate VIN. The device is targeted at always-on microcontroller supply rails in industrial sensors, e-meters, and automotive body modules.
The TPS7A16 uses a PNP-pass architecture with a precision bandgap reference and internal charge-pump drive. Its 60 V rating supports 24 V and 48 V industrial buses plus automotive load-dump transients (with external TVS). The 5 µA IQ makes it ideal for battery-powered applications where standby time dominates, and the PG output allows MCU-driven sequencing without extra supervisory ICs.
Typical applications include 24 V industrial sensor rails, smart-metering data-logger supplies, battery management housekeeping rails, and automotive body-controller always-on logic. The wide VIN also suits fire/security panels and HVAC controllers. In every case the regulator sits between a noisy or high-voltage bus and a low-power MCU/analog domain.
When designing with the TPS7A1633DGNT, observe the minimum VIN-VOUT headroom for regulation at 100 mA and place the input/output ceramic capacitors close to the IC pins. Tie PG to a logic-level pull-up, and use the EN pin for sequenced power-up. The exposed pad must be soldered to a sufficient copper area for thermal performance.

일반적인 애플리케이션
TPS7A1633DGNT 적합 용도: 7 애플리케이션s: 24V Industrial Sensor Rails, Smart Meter / Data-Logger Supplies, Battery Management Housekeeping Rails, Automotive Body-Controller Always-On Logic, Fire/Security Panel Backup Rails, HVAC Controller Logic Supply, Remote IoT Sensor Nodes.
24V Industrial Sensor Rails
The TPS7A1633DGNT fits 24 V industrial sensor rails because its 3 V to 60 V input range directly accepts 24 V nominal bus voltage with headroom for transients, while its 5 µA quiescent current lets the sensor remain always-on without draining the field-supply budget. The fixed 3.3 V output matches typical MCU and IO-link transceiver supply rails. Designers place a 1 µF ceramic at VIN and a 1 µF ceramic at VOUT, both within 5 mm of the IC, and use the exposed pad as a thermal pad tied to a 100 mm² copper pour.
추천
Smart Meter / Data-Logger Supplies
The TPS7A1633DGNT is well suited for smart-meter and data-logger housekeeping rails where 5 µA IQ directly extends battery life across years of standby. The 60 V input withstands rectified mains-derived rails in capacitor-drop supplies, and the open-drain PG output can wake the host MCU only after the rail is stable. Power-rail sequencing is straightforward via the EN pin, which the MCU can drive after its internal POR completes. In typical AMR/NMR designs this LDO feeds the metrology MCU and RTC from a single 3.6 V lithium battery with optional external backup.
추천
Battery Management Housekeeping Rails
In a battery management system (BMS), the TPS7A1633DGNT powers the low-power housekeeping MCU and isolation logic while a separate supply handles the AFE. Its 1 µA shutdown current is critical when the pack enters shipping/sleep mode, and the 60 V input rating tolerates the full pack voltage of 13-series Li-ion stacks. The PG pin can be wire-ORed with the charger's PG to gate downstream regulators. Designers should add a TVS such as SMBJ58A at VIN for automotive load-dump protection if the pack sees 12 V system transients.
추천
Automotive Body-Controller Always-On Logic
Automotive body controllers need a regulator that is always alive even when the ignition is off, drawing microamps from the 12 V battery. The TPS7A1633DGNT and its Q1 suffix variant TPS7A1633QDGNRQ1 deliver exactly this behavior, with the Q1 part qualified to AEC-Q100 for body-electronics use. The 60 V input range handles 12 V jump-start and 24 V truck-battery environments, and the open-drain PG output drives an MCU interrupt to wake the system when the rail collapses. Place the part near the battery feed with reverse-battery and load-dump protection upstream.
추천
Fire/Security Panel Backup Rails
Fire and security panels must retain functionality across brownouts and battery-backed standby. The TPS7A1633DGNT's wide 3 V to 60 V input accepts the rectified 24 V backup-rail voltage while its 5 µA IQ is negligible against the panel's standby budget. The PG output gives the supervisory MCU deterministic status of the regulated 3.3 V rail before enabling downstream loads. The HVSSOP-8 footprint also helps designers fit the regulator alongside multi-rail backup converters in a compact enclosure.
추천
HVAC Controller Logic Supply
In HVAC controllers, the TPS7A1633DGNT supplies the always-on thermostat logic from a 24 VAC rectified rail or a 48 V low-voltage DC bus. Its 60 V input rating tolerates rectified 24 VAC peaks (≈34 V) plus margin, and the 5 µA IQ ensures the wall-transformer budget is not consumed during the long standby hours between user interactions. The EN pin is typically tied high through a 100 kΩ resistor for default-on operation, while PG can interrupt the Wi-Fi/BLE radio on partial brownouts. Designers should add Y-cap-resistor discharge protection upstream of the LDO.
추천
Remote IoT Sensor Nodes
Battery-powered IoT sensor nodes spend most of their life in deep sleep, where the LDO's quiescent current directly determines the field-replacement interval. The TPS7A1633DGNT's 1 µA shutdown current and 5 µA IQ preserve the lithium primary cell for years, while the 60 V input range tolerates the open-circuit voltage of small solar panels. The PG output can gate the radio's transmit current until the LDO is stable, preventing brown-out resets. Place the LDO close to the battery feed with input TVS protection against ESD and reverse polarity.

설계 노트
Estimated: At VIN=24 V, VOUT=3.3 V, and 100 mA load, the TPS7A1633DGNT dissipates (24-3.3) × 0.1 ≈ 2.07 W. The HVSSOP-8 (DGN) PowerPAD has θJA in the 40-50 °C/W range with the EP soldered to a 100 mm² copper pour on a 1 oz 4-layer board, giving a junction-to-ambient rise of roughly 80-100 °C above ambient. Without the EP properly soldered, θJA rises sharply and the part will overheat in 24 V applications. Always solder the exposed pad to a continuous copper pour on the top layer (and via-stitched to inner layers) for production designs.
Place a 1 µF X7R ceramic capacitor on VIN (within 5 mm of the pin) and a 1 µF X7R ceramic on VOUT (within 5 mm of the pin). Use 0402 or 0603 sizes to minimize loop area. Add a 0.1 µF high-frequency bypass in parallel if the upstream source is a switching pre-regulator. Tie PG to a logic-level pull-up resistor (typically 100 kΩ to 1 MΩ to VOUT or to the MCU's VCC) and place the PG-delay capacitor (typically 10-100 nF) close to the PG pin. Route EN away from noisy switching traces to avoid false enables during transient spikes.
Do not assume the TPS7A1633DGNT survives automotive load-dump without external protection. Add an SMBJ58A or similar TVS at VIN, plus a reverse-battery P-FET or Schottky diode, for 12 V/24 V automotive use. Do not float EN if you want default-on operation - the EN pin must be tied high through a resistor (10-100 kΩ), not left floating, otherwise the part may intermittently enable from leakage. Avoid using electrolytic output capacitors with ESR below the LDO's minimum ESR requirement; X7R ceramics are recommended. Finally, ensure VIN does not exceed 60 V even transiently, or the device will enter permanent overvoltage lockout.
Keep the input capacitor, output capacitor, and exposed pad on the same top-layer copper with via stitching around the EP for thermal spreading. Avoid routing high-current load return paths under the LDO to prevent ground-bounce coupling into the reference. For 24 V-to-3.3 V designs where the LDO dissipates >1 W, dedicate a top-layer copper island to the EP and stitch it to inner ground planes with at least 4 thermal vias. Minimize the trace length from PG to its pull-up resistor to avoid false PG asserts during fast VIN transients.
