AS1362

AS1361/AS1362 150mA/300mA, Ultra-Low-Noise, High-PSRR Low Dropout Regulators, with POK www.datasheet4u.com D a ta S he e t 1 General Description The AS1361/AS1362 are ultra-low-noise, low-dropout linear regulators specifically designed to deliver up to 150/300mA continuous output current, and can achieve a low 140mV dropout for 300mA load current. The LDOs are designed and optimized to work with low-cost, smallcapacitance ceramic capacitors. The devices are available as the standard products listed in Table 1. Table 1.

Preset Output Voltages: 1.5 to 4.5V (in 50mV steps) Output Noise: 9µVRMS @ 100Hz to 100kHz Power-Supply Rejection Ratio: 92dB @ 1kHz Low Dropout: 140mV @ 300mA Load Power-OK Output Stable with 1µF Ceramic Capacitor for any Load Guaranteed 150/300mA Output 1.25V Internal Reference Extremely-Low Quiescent Current: 40µA Excellent Load/Line Transient Overcurrent and Thermal Protection TSOT23 6-pin Package An integrated P-channel MOSFET pass transistor allows the devices to maintain extremely low quiescent current (40µA). The AS1361/AS1362 uses an advanced architecture to achieve ultra-low output voltage noise of 9µVRMS and a power-supply rejection-ratio of better than 80dB (up to 10kHz). An active-Low, open-drain power-ok output indicates if the output voltage is within regulation. The AS1361/AS1362 requ...
