CAT6219 - 500 mA CMOS LDO Regulator

Description

The CAT6219 is a 500 mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes.

The quick-start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn-on time of just 150 ms.

Features

  • include current limit and thermal protection. The LDO is available in fixed and adjustable output in the low profile (1 mm max height) 5.
  • lead TSOT23, 6.
  • pad 1.5 mm x 1.5 mm WDFN and in the 6.
  • pad 2 mm x 2 mm TDFN packages. Features.
  • Guaranteed 500 mA Peak Output Current.
  • Low Dropout Voltage of 300 mV Typical at 500 mA.
  • Stable with Ceramic Output Capacitor.
  • External 10 nF Bypass Capacitor for Low Noise.
  • Quick.
  • start Feature.

CAT6219 LDO Regulator - CMOS 500 mA Description The CAT6219 is a 500 mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes. The quick-start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn-on time of just 150 ms. With zero shutdown current and low ground current of 55 mA typical, the CAT6219 is ideal for battery-operated devices with supply voltages from 2.3 V to 5.5 V. An internal under voltage lockout circuit disables the output at supply voltages under 2.15 V typical. The CAT6219 offers 1% initial accuracy and low dropout voltage, 300 mV typical at 500 mA.
