# TLV75533PDBVR (Component)
## Description
Linear Voltage Regulator IC Positive Fixed 1 Output 500mA SOT-23-5
The TLV75533PDBVR is a low-dropout (LDO) linear voltage regulator designed to provide a stable 3.3 V output from a higher input voltage source. It features ultra-low quiescent current and high power-supply rejection ratio (PSRR), making it ideal for battery-powered and noise-sensitive applications such as IoT devices, portable electronics, and RF circuits. The device is optimized for fast transient response and stable operation with small ceramic output capacitors.
