MP20048 Datasheet, PDF (1/10 Pages) Monolithic Power Systems – Capacitor-Free, 250mA, Low Dropout Voltage Regulator

The Future of Analog IC Technology
DESCRIPTION
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. It can get any value of output
from 1.234V to 5V. The benefit of this product is
that it can operate without any capacitors.
The MP20048 uses an advanced BICMOS
process to yield high precision. It also delivers
very low dropout voltage and low ground pin
current. It integrates the thermal-off and current
limit block to protect the devices from damage.
The MP20048 is available in a TSOT23-5
package.
