DESCRIPTION
Low external parts counts (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the UTC L5201-xx series ideally suited for small, battery-powered applications. A charge-pump architecture maintains constant switching frequency to zero load and reduces both output and input ripple. The UTC L5201-xx series have thermal shutdown capability to escape the device damaged from a continuous short-circuit. With built-in soft-start circuitry to prevents excessive current flow at VIN during start-up. High switching frequency enables the use of small ceramic capacitors. A low-current shutdown feature disconnects the load from VIN and reduces quiescent current to <1µA. The L5201-ADJ is available in MSOP-8 package and L5201-fixed in SOT-26 and TSOT-26 package. 1 4 2 3 SOT-26 6 5 1 2 3 TSOT-26 *Pb-free plating product number: L5201LFEATURES
