Part UM1770
Description VLDO Linear Regulator
Feature UM1770 500mA, Micropower, VLDO Linear R egulator UM1770Y-xx SOT89-5 UM1770DA-xx DFN6 2.
0×2.
0 General Description Th e UM1770 series are VLDO (very low drop out) linear regulators designed for low power portable applications.
Typical o utput noise is only 90μVRMS (Fixed Out put, VOUT=1.
0V) and maximum dropout is just 320mV at the load current of 500mA .
The internal P-channel MOSFET pass tra nsistor requires no base current, allow ing the device to draw only 250μA duri ng normal operation at the maximum load current of 500mA.
Other features inclu de high output voltage accuracy, excell ent transient res .
