IRU1502-33
MICROPOWER 1A LOW DROPOUT PMOS VOLTAGE
REGULATOR FEATURES
Stable with Ceramic Capacitor Small, Space Saving MLPM 6-Pin Package Guaranteed < 1V Dropout at Full Load Current Fast Transient Response Ultra-Low Ground Current Output Current Limiting Built-In Thermal Shutdown
DESCRIPTION
The IRU1502-33 is a PMOS low dropout, linear
regulator and it is capable of supplying 1A of continuous current over line and temperature range. The IRU1502-33 is stable with low value ceramic capacitors, ensures low noise operation, improves load transient response and enables a smaller circuit size. IRU1502-33 features ultra low noise, fast start-up and an excellent time and load response. This device also includes built-in output protection with both current limit and thermal shutdown.
