LM3880QMF-1AC

Texas Instruments · Supervisor And Reset ICs · SOT-23-6

LM3880QMF-1AC from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VCC	power_in	Input supply pin, operating range 2.7 V to 5.5 V relative to GND, with absolute maximum of -0.3 V to 6 V; it should be placed as close as possible to the input supply, and a 0.1 µF ceramic bypass is suggested where noise is present.
2	GND	power_in	Ground reference pin for the sequencer and the reference for the VCC supply and EN and FLAG voltage limits.
3	EN	input	Precision enable input with a 1.25 V (typical, 1.0 V to 1.4 V) threshold and an internal 7 µA pull-up; it must be kept below the threshold until VCC has risen above its minimum operating voltage, and the datasheet recommends not connecting it directly to VCC.
4	FLAG3	output	Open-drain output 3 that needs an external pull-up (typically 100 kΩ) to a supply not exceeding VCC + 0.3 V, with a maximum on-state output current of 50 mA and a low-level output of 0.4 V max at 1.2 mA.
5	FLAG2	output	Open-drain output 2 that needs an external pull-up (typically 100 kΩ) to a supply not exceeding VCC + 0.3 V, with a maximum on-state output current of 50 mA and a low-level output of 0.4 V max at 1.2 mA.
6	FLAG1	output	Open-drain output 1 that needs an external pull-up (typically 100 kΩ) to a supply not exceeding VCC + 0.3 V, with a maximum on-state output current of 50 mA and a low-level output of 0.4 V max at 1.2 mA.
