LP2953AIM/NOPB

Стабилизатор с малым падением напряжения, регулируемый, -20В до 30В (Vin), 470мВ, 1.23В до 29В/250мА.

The LP2953AIM/NOPB is an adjustable micro-power low-dropout Voltage Regulator with very low quiescent current and very low-dropout voltage. It is ideally suited for battery-powered systems. Furthermore, the quiescent current increases only slightly at dropout, which prolongs battery life. It retains all the desirable characteristics of the LP2951, but offer increased output current, additional features and an improved shutdown function. The automatic output discharge pulls the output down quickly when the shutdown is activated. The error flag goes low if the output voltage drops out of regulation. The internal voltage reference is made available for external use, providing a low temperature coefficient (20ppm/°C) reference with very good line (0.03%) and load (0.04%) regulation. Auxiliary comparator included with CMOS and TTL-compatible output levels. It can be used for fault detection, low-input line detection and so on.
