TPS78001DDCR

TEXAS INSTRUMENTS  TPS78001DDCR  芯片, 稳压器, LDO, 可调, 1.22V-5.25V, 150mA, TSOT-23-5

DESCRIPON

The TPS780 family of low-dropout LDO regulators offer the benefits of ultralow power IQ = 500nA, miniaturized packaging 2×2 SON-6, and selectable dual-level output voltage levels. An adjustable version is also available, but does not have the capability to shift voltage levels.

The VSET pin allows the end user to switch between two voltage levels on-the-fly through a

microprocessor-compatible input. This LDO is designed specifically for battery-powered  applications where dual-level voltages are needed. With ultralow IQ 500nA, microprocessors, memory cards, and smoke detectors are ideal applications for this device.
