LP2967

LP2967 Dual Micropower 150 mA Low-Dropout Regulator in micro SMD Package April 2003 LP2967 Dual Micropower 150 mA Low-Dropout Regulator in micro SMD Package General Description The LP2967 is a 150 mA, dual fixed-output voltage regulator designed to provide ultra low-dropout and low noise in battery powered applications. Using an optimized VIP (Vertically Integrated PNP) process, the LP2967 delivers unequalled performance in all specifications critical to battery powered designs: Dropout Voltage: Typically 240 mV at 150 mA load, and 6 mV at 1 mA load for each output. Ground Pin Current: Typically 1 mA at 150 mA load, and 200 µA at 1 mA load for each output. Enhanced Stability: The LP2967 is stable with output capacitor ESR as low as 5 mΩ, which allows the use of ceramic capacitors on the output. Sleep Mode: Less than 2 µA quiescent current when SD pins are pulled low. Smallest Possible Size: micro SMD package uses absolute minimum board space. Precision Output: 1.25% tolerance. Low Noise: By adding a 100 nF bypass capacitor, output noise can be reduced to 30 µV (typical). Multiple voltage options, from 1.8V to 5.0V, are available. Consult factory for custom voltages.
