LM150/LM350A/LM350 3-Amp Adjustable Regulators
The LM150 series of adjustable 3‑terminal positive voltage regulators provide up to 3 A output over a 1.2 V to 33 V range. They include internal overload protection such as current limit, thermal overload, and safe‑area protection, and can be used in a variety of applications from power supplies to battery chargers.

It also includes a life‑support policy disclaimer and contact information for National Semiconductor.
| Output Current | 3 A |
|---|---|
| Output Voltage Range | 1.2 V – 33 V |
| Reference Voltage | 1.25 V |
| Line Regulation (typ) | 0.01 %/V |
| Ripple Rejection | 86 dB |
| Package Types | Steel TO‑3 (K) and TO‑220 plastic (T) |
The LM150 develops a nominal 1.25 V reference voltage between the output and adjustment terminals.
Devices with a K suffix use a standard Steel TO‑3 metal can package, while those with a T suffix use a TO‑220 plastic package.
The regulators are guaranteed to deliver up to 3 A of output current.
