Hi everyone,
I need help to find out the part number of 2 smd part, details below.
1)
Marking code :- AQM
Package :- SC-70 5 pin
Function :- voltage regulator 3VDC
Pin function :- 1-2-3 are GND, 4-VIN, 5-VOUT
2)
Marking code :- OBG
Package :- SC-70 6 pin
Function :- voltage regulator 5VDC 800mA
Pin function :- 1 is connected to resistor divider mid point (one resistor point to pin 6 and second resistor point to GND),2-GND, 3-connected to microcontroller pin, 4-VOUT, 5-VIN, 6-connected to microcontroller pin.
I am having problem with this device in one instrument, i want to replace this but not able to find the part code.
Please someone help me out.
