The UTC LR1102 families are CMOS-based voltage regulator
ICs with extremely low supply current, high output voltage
accuracy, high Ripple Rejection and chip enable circuit.
These ICs performance are excellent and with SOT-25
package, thus these ICs are very suitable for hand-held
communication equipment.
