The LM2936-3.0 is an ultra-low quiescent current regulator from TI. It has an output voltage of 3V, an output current of 50mA, and a static current of less than 20µA. It is ideal for automotive and other battery operated systems. The LM2936-3.0 has a maximum operating voltage of 40V, a -40˚C to +125˚C operating temperature range, and ±3% output voltage tolerance over the entire output current, input voltage, and temperature range. The LM2936-3.0 is available in TO-92, SO-8, SOT-223, and TO-252 packages.
The LM2936-3.0 is an ultra‑low quiescent current, low‑dropout linear regulator delivering a fixed 3.0 V output at up to 50 mA. It offers low dropout voltage, reverse‑battery protection, internal current limiting, and thermal shutdown, making it suitable for automotive and other battery‑operated systems.
The document includes absolute maximum ratings, electrical characteristics, typical performance curves, connection diagrams for multiple package styles (TO‑92, SO‑8, SOT‑223, TO‑252), and physical dimensions. Application notes describe layout recommendations, shutdown pin operation, and thermal considerations for surface‑mount packages.
| Output Voltage | 3.0 V ±3 % |
|---|---|
| Dropout Voltage | Typical 200 mV |
| Maximum Input Voltage (Survival) | +60 V, -50 V |
| Operating Temperature Range | -40 °C to +125 °C |
| Reverse Battery Protection | Enabled |
| Thermal Shutdown | Internal, typical 150 °C |
| Shutdown Pin (LM2936BM) | Logic High >2.0 V turns off output |
The typical dropout voltage is about 200 mV.
The device can survive up to +60 V and down to –50 V on its input.
Yes, the LM2936BM version includes a shutdown pin; a logic high (>2.0 V) disables the output.
