LM27761DSGR Integrated Circuit Chip Low-Noise Regulated Inverter with Integrated LDO

Product Description Of LM27761DSGR
LM27761DSGR low-noise regulated switched-capacitor voltage inverter delivers a very low-noise adjustable output for an input voltage in the range of 2.7 V to 5.5 V. Four low-cost capacitors are used in the application solution to provide up to 250 mA of output current. The regulated output for the device is adjustable between −1.5 V and −5 V. LM27761DSGR operates at 2-MHz (typical) switching frequency to reduce output resistance and voltage ripple. With an operating current of only 370 µA (charge-pump power efficiency greater than 80% with most loads) and 7-µA typical shutdown current, LM27761DSGR provides ideal performance when driving power amplifiers, DAC bias rails, and other high-current, low-noise voltage applications.
