Linear Technology LT3464
The LT3464 has a typical current limit of 115mA as well as fast switching speed to allow the use of a chip inductor and small ceramic capacitors. The internal PNP disconnects the output load from the input during shutdown, and also provides output short-circuit protection. This device features a low 25µA quiescent current, which is further reduced to less than 1µA in shutdown.| Part No. | LT3464 |

The small package size, high level of integration, and the use of tiny SMT components yield a solution size of less than 40mm2. An auxiliary reference input allows the user to override the internal 1.25V feedback reference with any lower value, allowing full control of the output voltage during operation.
