60mA High Voltage Linear Regulator
LD6903
6/6/06
REV:01
General Description
The LD6903 is a high voltage, micropower linear regulator,
which features wide input voltage, low-noise, low-dropout
and low-quiescent current. The precision of feedback
reference voltage is within ±1.5% and output current is up to
60mA.
The LD6903 is available in a space saving SOT23-6 or
SC70-6 package.
