LDO with 1.8µA tail current and a 24V-capable input

AP7380 is a 1.8µA (3µAmax) quiescent current low-dropout (500mV at 50mA, 1.5Vmax at 150mA) regulator with 3.5-24V input voltage range.

Diodes AP7380

Output voltage is fixed, with a choice of 3.0, 3.3, 4.15, 4.4 and 5.0V, at 1% tolerance.

They are all available with or without an enable pin in a SOT25 package, or without an enable pin in SOT89. When de-enabled, quiescent current is 10nA typical.

Diodes AP7380According to the firm, it is compatible with low-ESR ceramic capacitors – which can be a cause of instability in low-drop regulators.

Applications are expected in USB-powered devices, portable devices, instrumentation, and industrial applications.
