Low Dropout LDO, ET55333B, ETEK Microelectronics

The ET55333B is a CMOS-based low-dropout (LDO), low-power linear regulator that delivers up to 500 mA with low dropout voltage, high ripple rejection, high output accuracy, and low supply current. The ET553XX consists of an accurate voltage reference, an error amplifier, a resistor network for voltage setting, a PMOSFET pass device, a thermal shutdown circuit, and a current limit circuit with short-circuit protection. The ET55333B uses an advanced CMOS process to minimize supply current. A low on-resistance PMOS pass device enables low dropout voltage. It also features an enable (EN) function to reduce power consumption and extend battery life.

Features

  • Excellent Load / Line Transient Response
  • Built-in Over Current Protection and Thermal Shutdown circuit
  • Built-in Inrush Current Suppression circuit and Current Limit
  • Built-in Auto-discharging circuit

Applications

  • Constant-Voltage Power Supply for Battery-Powered Device
