LT1761 - 100mA, Low Noise, LDO Micropower Regulators In SOT-23
The LT1761 series are micropower, low noise, low dropout Regulators With an external 0.01F bypass capacitor, output noise drops to 20VRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 20A quiescent current makes them an ideal choice. In shutdown, quiescent current drops t 52b o less than 0.1A. The devices are capable of operating over an input voltage from 1.8V to 20V, and CAN supply 100mA of output current with a dropout voltage of 300mV. Quies-cent current is well controlled, not rising in dropout as it does with many other Regulators The LT1761 Regulators are stable with output capacitors as low as 1F. Small ceramic capacitors CAN be used without the series resistance required by other Regulators
Internal protection circuitry includes reverse battery pro-tection, current limiting, thermal limiting and reverse current protection. current protection. The device is available in fixed output voltages of 1.2V, 1.5V, 1.8V, 2V, 2.5V, 2.8V, 3V, 3.3V and 5V, and as an adjustable device with a 1.22V reference voltage. The LT1761 Regulators are available in the 5-lead SOT-23 package.
