LE33CZ-AP ST Linear Voltage Regulator | TO-92-3 | 3.3V Output, 100mA

Product Overview

The LE33CZ-AP from STMicroelectronics is a fixed-output low-dropout (LDO) linear voltage regulator designed to deliver a stable 3.3V output with a maximum current of 100mA. Housed in a TO-92-3 package, this device offers excellent line and load regulation, making it suitable for battery-powered and low-power applications. The LDO architecture ensures minimal dropout voltage, typically 0.2V at 100mA, enabling efficient operation even when the input voltage is close to the output.
