ERY LOW DROP AND LOW NOISE VOLTAGE REGULATO WITH INHIBIT FUNCTION
1/12January 2003 VERY LOW DROPOUT VOLTAGE (280mV 150mA AND 7mV AT 1mA LOAD) VERY LOW QUIESCENT CURRENT (2.2mA
TYP. AT 150mA LOAD AND 75μAAT NO
LOAD) OUTPUT CURRENT UP TO 150mA LOGIC CONTROLLED ELECTRONIC
SHUTDOWN OUTPUT VOLTGAEOF 1.8,2.5,2.8,3,3.1,
3.2, 3.3, 3.5, 3.6, 3.8,4, 4.7,5V INTERNAL CURRENT AND THERMAL LIMIT AVAILABLEIN ± 1% TOLLERANCE (AT 25°C,
AVERSION) LOW OUTPUT NOISE VOLTAGE 30μVrms SMALLEST PASCKAGE SOT23-5L TEMPERATURE RANGE: -40°C TO 125°C
DESCRIPTIONThe LD2985isa 150mA fixed output voltage
regulator. The ultra low drop voltage and the low
quiescent current make them particularly suitable
for low noise, low power applications, andin
battery powered systems. In sleep mode
quiescent currentis less than 1μA when INHIBIT
pinis pulled low. Shutdown Logic Control Function availableon pin3 (TTL compatible). This means
that when the deviceis usedas local regulator,it possibleto puta partof the boardin standby,
decreasing the total power consumption. internal capacitor connectedto the bypass pin OUT 30mVrms.
Typical application arein cellular phone, palmtop/
laptop computer, personal fdigital assistant (PDA),
personal stereo, camdorder and camera.
