L1186_10

UNISONIC TECHNOLOGIES CO., LTD L1186 600mA CMOS LDO 5 Preliminary CMOS IC 4 DESCRIPTION The UTC L1186 is a COMS positive linear regulator. One of its features is the very low quiescent current typical as low as 30μA and its dropout voltage is extremely low with 600mA output current. The internal circuit includes thermal shutdown and current fold-back to prevent device failure when the circuit is operated in the bad conditions. In application, the UTC L1186 needs a low noise, regulated supply. For stable operation, the output capacitance value should be 2.2μF or more. The UTC L1186 is an ideal for battery applications, such as instrumentations, portable electronics, wireless devices, cordless phones, PC peripherals, and battery powered widgets. 1 2 3 SOT-25 1 SOP-8 FEATURES * Accurate to Within 1.5% * Quiescent Current: 30μA * Internal Over-Temperature Shutdown * With Current Limiting * Internal Short Circuit Current Fold-Back * With Noise Reduction Bypass Capacitor * Has Power-Saving Shutdown Mode * Very Low Temperature Coefficient ORDERING INFORMATION Ordering Number Lead Free Halogen Free L1186L-xx-AF5-R L1186G-xx-AF5-R L1186L-xx-S08-A-R L1186G-xx-S08-A-R L1186L-xx-S08-B-R L1186G-xx-S08-B-R Note: xx: Output Voltage, refer to Marking Information.
