TPR1033
Low quiescent current LDO with 3.3V output, 300mA capability, and enable function.
Product Overview
Description
The TPR1033 is a low quiescent current LDO regulator providing a fixed 3.3V output with 300mA current capability. It features ultra-low quiescent current of 2µA, maximizing battery life in standby mode.
The LDO operates from a wide 2.5V to 16V input voltage range and includes an enable pin for power management. It requires only 1µF ceramic output capacitor for stability.
With low dropout voltage of 250mV at 300mA and excellent load transient response, the TPR1033 is ideal for battery-powered applications, IoT devices, and portable electronics.
