ELM9827BA

ELM9827BA is a kind of CMOS voltage regulator. It consists of reference voltage, error amplifier, short-protected control transistor, output voltage setting resistor and so on. The typical applications include battery-operated devices, palmtops, cameras and vedio recorders, reference voltage sources.There are some features as follows. First is high accuracy which is ±2.0%. The second is load stability which is 10 mV typical when 1 mAIOUT50 mA. Then is input stability which is 0.1%/V at IOUT=50 mA. Next is output voltage temperature coefficient which is ±ppm/. The fifth is very low power operation. The last one is very small package which includes SOT-89 and SOT-23.

What comes next is about the absolute maximum ratings of ELM9827BA. The VIN (input voltage) is 12 V. The VOUT (output voltage) is from VIN+0.3 to VSS-0.3 V. The IOUT (output current) is 200 mA. The PD (power dissipation) is 300 mW for SOT-89 package and 200 mW for SOT-23 package. The TOP (operating temperature) is from -30 to 80. The TSTG (storage temperature) is from -40 to +125.

The following is about the electrical characteristics (TOP=25) of ELM9827BA. The minimum VOUT (output voltage) is 2.646 V, the typical is 2.700 V and the maximum is 2.754 V at VIN=4.7 V, IOUT=1 mA. The minimum IOUT (output current) is 40 mA at VIN=3.3 V. The typical VOUT/IOUT (load stability) is 10 mV and the maximum is 20 mV at VIN=4.7 V, 1 mAIOUT50 mA. The typical Vdif (input/output voltage differential) is 90 mV and the maximum is 120 mV at IOUT=10 mA. The typical ISS (current consumption) is 4.0A and the maximum is 7.0A at VIN=4.7 V, no-load. The maximum VIN (input voltage) is 10 V.
