ST offers a wide range of low and medium power LDO regulators featuring ultra-low dropout and fast transient response characteristics. The ultra-low dropout series of LDOs simplifies the design of high-efficiency, cost-effective linear power management (from 50 mA to 3 A of continuous load current), ideal for DSPs, MCUs and FPGAs.
LDCL015 series of capless ultra-low-drop linear regulators
The LDCL015 series of LDOs are ideal for handheld and space-sensitive applications. Available in fixed (3.3 V) and adjustable output voltages (from 0.8 V in 100 mV steps), they provide 150 mA of output current from an input voltage ranging from 1.8 V to 5.5 V, with a typical dropout voltage of 50 mV (at 100 mA load). No input or output capacitor is needed. Available in an SOT23-5L package, they include a logic-controlled enable function, short-circuit and thermal protection.
