15 mA charge pump for tight supply rails
The LM2767M5/NOPB: The output is adjustable from a 3.6 V minimum up to 11 V, which makes it useful for generating a small bias rail or a doubled voltage from a low-voltage battery. At 11 kHz switching frequency, the output ripple sits in the audio band — a ceramic output cap with low ESR keeps the ripple amplitude manageable, but the noise spectrum is something to budget for if the downstream load is an analog front-end.
What the 15 mA rating means on the bench
The 15 mA current-output ceiling is the continuous rating, not a burst figure. The 11 kHz switching frequency is fixed — no external sync or frequency-adjust pin. That puts the fundamental ripple at 11 kHz and its harmonics into the tens of kilohertz. A 1 µF ceramic output cap with 10 mΩ ESR keeps the ripple under 50 mV at full load, but if the load draws less than 1 mA the part may skip pulses and the ripple spectrum widens.
Active lifecycle and sourcing posture
That means it is still a valid choice for new designs and there is no forced migration risk. No pin-compatible second-source or official successor is listed — the part is a single-source charge pump in this package.
The SOT-23-5 (SC-74A) package is a standard 5-pin footprint with 0.95 mm pitch. The pinout is simple: VIN, GND, VOUT, and two capacitor pins for the flying capacitor and the output capacitor. No exposed pad — thermal relief is through the pins themselves, so the copper trace width to the VOUT and GND pins matters more than usual for a small regulator. The part is available in Tape & Reel (TR) or Cut Tape (CT) options, which covers both production reels and prototype quantities. The CT option is handy for bench builds without committing to a full reel.
