LE33CZ Description

Short technical summary and product information.

The STMicroelectronics LE33CZ is a linear voltage regulator designed for low-noise, low-power applications, particularly in battery-powered systems. It features a very low dropout voltage of 0.2V typical and a low quiescent current of 0.5mA in ON MODE with no load.

 

This regulator offers a fixed output voltage of 3.3V and can supply an output current of up to 100mA. It includes internal current and thermal limit protection features. Stability is achieved with a small 2.2µF capacitor. The device operates over a wide temperature range of -40°C to 125°C.

 

The LE33CZ is available in a TO-92 package, suitable for through-hole mounting. Its pin-to-pin compatibility with older L78Lxx series makes it an easy replacement. The device also offers good supply voltage rejection of 80dB typical.

 

Key electrical characteristics include a maximum dropout voltage of 0.5V at 100mA and a PSRR ranging from 80dB to 60dB across 120Hz to 10kHz. The output voltage tolerance is ±1% or ±2% at 25°C.
