Low Dropout (LDO) Linear Regulators

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.
