6.10 Low Drop Out Regulators
6.10.1 General
These LDO’s are designed to supply sensitive analogue circuits, audio devices, AD and DA converters, micro-controller and other
peripheral devices.
The design is optimised to deliver the best compromise between quiescent current and regulator performance for battery powered
devices.
Stability is guaranteed with ceramic output capacitors of 1μF +/-20% (X5R) or 2.2μF +100/-50% (Z5U). The low ESR of these caps
ensures low output impedance at high frequencies. Regulation performance is excellent even under low dropout conditions, when the
power transistor has to operate in linear mode. Power supply rejection is high enough to suppress high ripple on the battery at the output.
The low noise performance allows direct connection of noise sensitive circuits without additional filtering networks. The low impedance of
the power device enables the device to deliver up to 150mA even at nearly discharged batteries without any decrease of performance.
