Dual LDO with Low Noise, Low IQ and High PSRR

ISL9014 is a high performance dual LDO capable of sourcing 300mA current from both outputs. The device has a low standby current and high-PSRR and is stable with output capacitance of 1µF to 10µF with ESR of up to 200mΩ.

Features

• Integrates two high performance LDOs

- VO1 - 300mA output

- VO2 - 300mA output

• Excellent transient response to large current steps

• Excellent load regulation: <1 voltage change across full range of load current

• High PSRR: 70dB @ 1kHz

• Wide input voltage capability: 2.3V to 6.5V

• Extremely low quiescent current: 45µA (both LDOs active)

• Low dropout voltage: typically 200mV @ 300mA

• Low output noise: typically 30µVRMS @ 100µA (1.5V)

• Stable with 1µF to 10µF ceramic capacitors

• Separate enable pins for each LDO

• Soft-start to limit input current surge during enable

• Current limit and overheat protection
