TLV713 - 150mA Capacitor-Free LDO with Enable | TI
MPN： TLV713 ✓ 啟用中TLV713 概覽
An LDO (low-dropout regulator) is a type of linear voltage regulator that maintains a stable, regulated output even when the input voltage is only marginally above the output voltage. Within the power-management IC hierarchy, the TLV713 occupies the point-of-load regulator tier, sitting downstream of bulk supplies or switching converters and feeding noise-sensitive analog and digital loads.
Key features include capacitor-free stability (stable with or without an output capacitor, saving PCB area and BOM cost), a very low dropout of 230 mV at 150 mA, and a typical output accuracy of 1%. The quiescent current is approximately 50 uA, and foldback overcurrent protection limits fault current. The TLV713P variant adds an active pull-down circuit that quickly discharges the output when disabled, useful for power sequencing and brief reset requirements.
Architecturally, the TLV713 uses a CMOS pass-element design optimized for excellent line and load transient performance despite the absence of an output capacitor. Fixed output voltage options in the series include (among others) 1.0 V, 1.8 V, and 2.5 V, indicated by suffix codes such as TLV71310PDBVT, TLV71318PDBVR, and TLV71325PDBVR. The enable pin permits rail gating in battery-powered systems, reducing standby current.
Typical applications include battery-powered portable devices, wearable electronics, wireless sensor nodes, and post-regulation of switching-converter outputs where a clean low-current rail is required without capacitor-induced startup delays.
Design consideration: because the device is stable without an output capacitor, load-transient spikes may be larger than with a decoupled design; adding a small ceramic capacitor is permitted when maximum transient performance is needed, per the TLV713 datasheet (SLVSBO6).

典型應用
TLV713 適用於 6 應用s: Battery-Powered Portable Devices, Wearable Electronics, Wireless Sensor Nodes, Post-Regulation of Switching Converters, MCU and Processor Point-of-Load Rails, IoT Smart Home Devices.
Battery-Powered Portable Devices
The TLV713 fits battery-powered portables because its approximately 50 uA quiescent current and enable pin minimize standby drain, while capacitor-free stability removes the output capacitor from the BOM. Placed as a point-of-load regulator downstream of a Li-ion rail or boost converter, it delivers up to 150 mA at 1% typical accuracy with only 230 mV dropout at full load. The foldback current limit protects against short circuits, and the SOT-23-5 footprint keeps layout area minimal for slim form factors.
推薦
Wearable Electronics
Wearable designs demand the smallest possible regulator solution; the TLV713 answers with a 1-mm x 1-mm 4-pin X2SON option and a 5-pin SOT-23 alternative, both stable without any output capacitor. Its 1% output accuracy keeps MCU and sensor rails within tolerance, while the active pull-down on the TLV713P variant ensures outputs discharge cleanly when the wearable sleeps. With 230 mV dropout at 150 mA, it maintains regulation as the battery discharges, and the enable pin allows the main MCU to gate power to sensors during standby.
推薦
Wireless Sensor Nodes
Wireless sensor nodes spend most of their life in sleep, so the TLV713's low ~50 uA quiescent current and enable-controlled rail gating directly extend battery life. The capacitor-free design removes ceramic capacitors that add height and cost to densely packed nodes. During transmit bursts the foldback overcurrent protection guards fault conditions, and 1% accuracy ensures the radio's supply stays within specification. Post-regulating a switching converter output with the TLV713 also cleans switching ripple from the radio supply rail.
推薦
Post-Regulation of Switching Converters
Switching converters introduce mV-level ripple; placing a TLV713 after a buck output provides a clean low-current analog rail without adding switching noise. Because the TLV713 is stable with no output capacitor, its startup is not delayed by capacitor charging, simplifying power sequencing in multi-rail systems. With 230 mV dropout at 150 mA and 1% accuracy, it is well matched to cleaning 3.3 V or 2.5 V analog supplies for ADCs and amplifiers where even modest ripple degrades signal-chain performance.
推薦
MCU and Processor Point-of-Load Rails
MCU cores and I/O rails in the 1.0 V to 2.5 V range map directly to TLV713 fixed-output options such as TLV71310PDBVT (1.0 V) and TLV71318PDBVR (1.8 V). The enable pin supports controlled power-up sequencing, and the TLV713P active pull-down discharges the rail quickly at shutdown, meeting reset requirements of microcontrollers. A 150 mA capacity comfortably covers low-power MCUs and their peripherals, while the SOT-23-5 package fits next to the MCU without extra layout area.
推薦
IoT Smart Home Devices
Smart home nodes combining radios, sensors, and small displays benefit from the TLV713's combination of low standby drain and zero-output-capacitor operation, cutting both sleep-mode current and component count. The 1% typical accuracy keeps sensitive RF front ends within their supply window for reliable wireless links, and foldback current limiting protects against wiring faults in fielded devices. The miniature X2SON package suits coin-cell or energy-harvesting form factors where every square millimeter counts.

設計說明
Confirm the exact ordering part number suffix: TLV713 output voltages are suffix-coded (TLV71310PDBVT = 1.0 V, TLV71318PDBVR = 1.8 V, TLV71325PDBVR = 2.5 V). Ordering the wrong suffix delivers the wrong rail voltage on an otherwise identical SOT-23-5 footprint. The 'P' suffix additionally enables active output pull-down.
Although the TLV713 is stable without an output capacitor, keep input/output traces short and place the regulator close to its load. For boards with long inductive input leads, add a small (0.1 uF to 1 uF) input ceramic capacitor for stability against input transients. When load-transient undershoot matters, TI permits adding a small output ceramic capacitor per datasheet SLVSBO6.
Account for foldback current limiting in fault scenarios: under a hard short the TLV713 limits fault current rather than delivering full 150 mA, which reduces die heating but means a latched fault may not self-recover. Tie EN to IN for always-on operation, or drive EN from a GPIO with a defined level - do not leave EN floating.
