ISL80410IBEZ - 40V 150mA Low-Iq LDO | Renesas Electronics
MPN: ISL80410IBEZ ✓ Hoạt độngISL80410IBEZ Tóm tắt
What is an LDO? A low-dropout regulator, or LDO, is a linear voltage regulator that maintains a stable output voltage using a pass transistor operating near its dropout region. The LDO is part of the linear-regulator, voltage-regulator, and power-management-IC hierarchy. Compared with a switching regulator, an LDO offers a simple topology and typically low output ripple, but its efficiency depends directly on the difference between input and output voltage and the load current.
Key features of the ISL80410IBEZ include its adjustable output, 150 mA rated output current, 18 µA no-load quiescent current, and +6 V to +40 V normal input range. The EN pin places the device into a low-quiescent-current state when shutdown behavior is required. The exposed pad in the 8-SOIC-EP package provides a thermal connection to the PCB, which is important because linear-regulator dissipation increases as input-to-output voltage difference and load current increase.
The ISL80410 is intended for applications that remain connected to a higher-voltage source but need a controlled local supply. Its low quiescent current helps preserve battery or standby power when the regulated rail is lightly loaded. The adjustable output allows the design to select the required rail voltage with external resistors, while the EN input supports controlled enable and disable sequencing in multi-supply systems.
Typical uses include industrial control and automation equipment, communications and networking equipment, test and measurement instruments, automotive or transportation electronics, and low-power embedded systems. The 40 V input capability is useful for 24 V industrial rails and other protected high-voltage systems, provided the regulator’s dropout, thermal, and output-voltage limits are respected.
A key design consideration is power dissipation. Estimated linear-regulator dissipation equals the input-to-output voltage difference multiplied by load current; for example, 12 V difference at 100 mA is approximately 1.2 W. Use the exposed pad as a thermal pad and provide adequate copper area according to the manufacturer’s thermal guidance.
This page combines verified manufacturer and distributor information with application guidance, parameter comparisons, and practical design notes to help engineers evaluate the ISL80410IBEZ for low-quiescent high-voltage regulation.

Ứng dụng tiêu biểu
ISL80410IBEZ phù hợp cho 6 Áp dụngs: 24 V Industrial Control Rails, Always-On Communications Equipment, Test and Measurement Instrumentation, Battery-Powered Embedded Systems, Automotive and Transportation Electronics, Sensor and Signal-Conditioning Power.
24 V Industrial Control Rails
The ISL80410IBEZ is suitable for generating a local regulated rail from a protected 24 V industrial supply because its normal input range is +6 V to +40 V and its output current is rated at 150 mA. The 18 µA no-load quiescent current helps limit standby consumption when a control module remains powered but is not actively processing signals. Designers should use the adjustable output to select the required logic voltage and verify dropout at the lowest input condition. Estimated dissipation is (VIN − VOUT) × IOUT, so a 24 V-to-5 V conversion at 150 mA requires attention to the exposed-pad thermal path and PCB copper area.

Always-On Communications Equipment
The ISL80410IBEZ fits always-on communications equipment where a low-power keep-alive rail must remain available without drawing substantial standby current. Its 18 µA no-load quiescent current is the central benefit, while the EN pin allows the designer to control operating state. A 150 mA output rating is suitable for low-to-moderate load circuitry, but it is not a replacement for a high-current transceiver supply. Verify the output-voltage range, input transients, and thermal dissipation at the maximum expected load. Keep the regulator’s input and output capacitors close to the device pins.
Được đề xuất
Test and Measurement Instrumentation
For test and measurement instruments, the ISL80410IBEZ can provide an adjustable local supply for control logic, sensor interfaces, or low-power analog sections. The +6 V to +40 V input range accommodates higher-voltage front-end environments, while the adjustable output supports instrument-specific rail planning. Its linear architecture can simplify filtering and reduce switching-converter ripple in sensitive sections. The main limitation is the 150 mA current rating: estimated power dissipation is (VIN − VOUT) × IOUT, so maintain adequate copper around the 8-SOIC-EP exposed pad and avoid sustained operation near the thermal limits.
Được đề xuất
Battery-Powered Embedded Systems
The ISL80410IBEZ is relevant to battery-powered or standby-heavy embedded systems when the regulator is connected continuously and low no-load consumption is valuable. Its 18 µA quiescent current helps preserve battery energy when the load is light, and the EN pin provides a controlled shutdown path when additional conservation is needed. The high-voltage input rating can simplify protection design for protected supplies, but the output current remains limited to 150 mA. Confirm the battery’s maximum voltage, startup behavior, output capacitance, and dropout margin before integrating the regulator.
Được đề xuất
Automotive and Transportation Electronics
The ISL80410IBEZ may be evaluated for 12 V or 24 V transportation-electronics subsystems where a high-input-voltage, low-quiescent regulator is needed for a small control or sensing domain. Its +6 V to +40 V normal input range provides margin above common automotive rails, while the EN input supports system-state control. However, the verified data does not confirm AEC-Q100 qualification, so automotive production use requires checking the exact ordering code and Renesas qualification documentation. Validate load transients, operating-temperature limits, reverse-battery protection, and exposed-pad thermal performance.
Được đề xuất
Sensor and Signal-Conditioning Power
The ISL80410IBEZ can supply low-power sensor and signal-conditioning circuitry when the system needs a simple, adjustable rail close to the measurement electronics. The 18 µA no-load current helps avoid loading lightly used sensing branches, and the positive adjustable output allows rail scaling from the external resistor network. The 150 mA rating is adequate for many sensor front ends but not for high-power actuators. Place input and output capacitors at the regulator pins, keep the feedback or divider routing short, and use the exposed pad for heat spreading when the input-to-output voltage difference is substantial.

Bảo phân biệt quan trọng

Ghi chú thiết kế
Estimated: linear-regulator dissipation is (VIN − VOUT) × IOUT. At 24 V input, 5 V output, and 150 mA, the estimated dissipation is 2.85 W. Route the exposed pad to a properly sized copper pour with thermal vias where the PCB design allows, and verify the junction-temperature calculation using the package thermal data in the Renesas datasheet.
Place the input and output capacitors as close as practical to the corresponding ISL80410IBEZ pins. Keep the feedback or output-adjustment resistor network close to the device to minimize noise pickup and routing resistance. Confirm the package land pattern and exposed-pad connection against the official Renesas package drawing rather than relying on a generic SOIC footprint.
Do not assume that a 40 V input rating permits operation at every output voltage and load condition. Check minimum dropout, output-current derating, enable timing, capacitor values, and absolute maximum limits in the datasheet. Also verify that the external resistor divider does not consume excessive current relative to the 18 µA no-load quiescent-current target.
