UNISONIC TECHNOLOGIES CO., LTD  
LD2985  
LINEAR INTEGRATED CIRCUIT  
VERY LOW DROP AND LOW  
NOISE VOLTAGE REGULATOR  
LOW ESR CAP. COMPATIBLE,  
WITH INHIBIT FUNCTION  
DESCRIPTION  
The UTC LD2985 is a 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, and in  
battery powered systems. In sleep mode quiescent current is less  
than 1μA when INHIBIT pin is pulled low. Shutdown Logic Control  
Function is available on pin 3 (TTL compatible). This means that  
when the device is used as local regulator, it is possible to put a part  
of the board in standby, decreasing the total power consumption.  
An external capacitor, CBYP=10nF, connected between bypass  
pin and GND reduce the noise to 30μVrms.  
Typical applications are in cellular phone, palmtop laptop  
computer, personal digital assistant (PDA), personal stereo,  
camcorder and camera.  
FEATURES  
* Very Low Dropout Voltage (280mV at 150mA and 7mV at 1mA load)  
* Very Low Quiescent current  
* Output Current up to 150mA  
* Logic Controlled Electronic Shutdown  
* Output Voltage of 1.5, 1.8, 2.5, 2.8, 2.85, 3, 3.1, 3.2, 3.3, 3.5, 3.6, 3.8, 4, 4.7, 5V  
* Internal Current and Thermal Limit  
* Low Output Noise Voltage 30μVrms
