LP5912-5.0DRVR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LP5912-5.0DRVR is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, providing a stable 5 V output with a maximum load current of 500 mA. It operates within an input voltage range of 1.6 V to 6.5 V and features a typical quiescent current of 30 µA. The device delivers high power supply rejection ratio performance of 40 dB at 100 kHz and maintains a typical dropout voltage of 150 mV under full load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Provides low noise performance suitable for RF and analog circuit applications without requiring external noise bypass capacitors
• Supports operation with small ceramic input and output capacitors, typically 1 µF each
• Includes integrated protection mechanisms such as thermal overload shutdown, short-circuit current limiting, and reverse current protection
