Product details

Dropout voltage and input range — headroom matters at 1.2 V out

Maximum dropout is 0.25 V at 250 mA. Input maximum is 5.5 V. Operating temperature range is -40°C to 125°C.

Package and footprint — 4-X2SON (1x1 mm)

The 4-X2SON measures 1x1 mm with an exposed pad for thermal transfer. The exposed pad must be soldered to a PCB copper plane to reach the rated 250 mA without thermal shutdown.

Lifecycle and sourcing — active, no LTB risk

Listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy schedule has been issued.

Frequently asked questions

Is LP5907SNX-1.2/NOPB obsolete?

No — the lifecycle status is Active (current production). No discontinuation notice or last-time-buy schedule has been issued.

Can I use LP5907SNX-1.2/NOPB with 5V input?

Yes — the maximum input voltage is 5.5 V, so a 5 V rail is within spec. However, dropout is only 0.25 V at 250 mA, so a 5 V input dissipates roughly 0.95 W at full load — the 4-X2SON package needs a good thermal plane to handle that.

What is the PSRR of LP5907SNX-1.2/NOPB?

PSRR is 90 dB at 100 Hz rolling off to 60 dB at 100 kHz. That covers the switching fundamental and lower harmonics of most DC-DC converters, making this LDO suitable for RF and analog supply filtering.
