ST’s low dropout (LDO) regulators offer an optimal combination of low dropout voltage, low quiescent current, fast transient response, low noise and good ripple rejection.
In particular, the ultra-low dropout (ULDO) regulators are ideal for battery-powered consumer applications as well as portable healthcare devices as a result of:
- ultra-low quiescent current (down to 1 µA) which extends battery run time
- tiny package options, including the 0.69 x 0.69 mm CSPs to achieve the smallest footprint
Signal fidelity is maintained over a wide range of input voltages and output currents all along the signal path, thanks to the high PSSR (power supply rejection rate) and low noise.
