MP20048 1.234-5V, 250mA Low Dropout Voltage Regulator TSOT23

The MPS MP20048 is a Low Dropout Voltage Regulator. It operates from a 1.234 V to 5 V input and is rated for 250 mA. It is supplied in a TSOT23 package.

The MP20048 is a kind of new low-dropout (LDO) voltage regulators which uses an NMOS as the pass element in a voltage-follower configuration.

Design Notes

Dissipation is (VIN − VOUT) × IOUT. Check it against the package thermal resistance at the real ambient temperature before committing to the full rated current.
Some low-noise LDOs require a minimum output capacitor ESR for loop stability — read the stability section before substituting a ceramic part.
Add a bypass capacitor on the reference pin where provided; it sets the output noise floor.
PSRR falls as the input-to-output differential shrinks, so headroom matters at low VIN.
