755P

Overview

The TLV755P is a low-dropout regulator (LDO) manufactured by Analog Devices Inc. It provides a maximum output current of 500 mA with an input voltage range of 1.45 V to 5.5 V. The device features a typical quiescent current of 25 µA and a maximum dropout voltage of 238 mV at full load. It offers high power supply rejection ratio (PSRR) of 46 dB at 100 kHz and maintains output accuracy within 1% across the operating temperature range. The component supports fixed output voltages from 0.6 V to 5 V and includes built-in soft-start and active output discharge functions.

Feature Summary

• Ultra-small package options including SOT-23-5, X2SON-4, and WSON-6 for minimized solution size
• Low quiescent current with enable functionality to reduce standby power consumption
• Internal soft-start mechanism limits inrush current during startup
• Active output discharge pulls down the output voltage quickly when shutdown

Applications

• Powering core voltages of modern microcontrollers (MCUs)
• Battery-powered portable electronic devices requiring low standby current
• Embedded systems needing stable regulated voltage from varying input sources
• Applications requiring fast output discharge for controlled start-up states

Procurement Notes

Verify the specific suffix code against official documentation to confirm pinout compatibility and thermal performance characteristics. Ensure the selected package variant matches the intended PCB layout constraints. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when minimizing board space and standby power are critical design constraints. The wide input voltage range accommodates single-cell lithium-ion or alkaline battery applications. Verify that the required output voltage is available in the fixed voltage variants to avoid external resistor networks. Consider thermal dissipation requirements based on the chosen package and ambient operating conditions.
