3.3V LDO Modules

3.3V LDO modules built on genuine Texas Instruments regulators. An LDO (low-dropout) module turns 5 V from USB, a charger or a battery into a steady 3.3 V for microcontrollers, sensors and radios. Every Ramanu module is a drop-in VIN–GND–VOUT board on an aluminium PCB, tested in Pune before it ships.
Which one do you need?

Everyday 3.3 V, the AMS1117 upgrade: TrueVolt74033 (TI TLV740P, 300 mA). No resets when USB sags, short-circuit safe.
Clean power for sensors, radios and audio: TrueVolt LN-7A2033 (TI TPS7A2033, 7 µVrms). For load cells, ADCs, mics, GPS and DACs.
Longest battery life: TrueVolt NP-7A0333 (TI TPS7A0333, 200 nA idle). For sensor nodes that sleep for months.
