TLV73315PDBVR

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

The TLV73315PDBVR is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, providing a stable 1.5 V output with a maximum load current of 300 mA. It operates within an input voltage range of 1.4 V to 5.5 V and features a typical power supply rejection ratio (PSRR) of 80 dB. The device maintains a quiescent current of 80 uA and exhibits a maximum dropout voltage of 600 mV. Line regulation is specified at 0.1 %/V, while load regulation is 110 uV/mA. It is housed in a SOT-23-5 package and supports surface-mount installation across a temperature range of -40 C to +85 C.
