LM117E Description

Short technical summary and product information.

The LM117E from Texas Instruments is a versatile adjustable 3-terminal positive voltage regulator. It is designed to supply currents of up to 1.5A over an output voltage range from 1.25V to 37V. This regulator is easy to use, requiring only two external resistors to set the output voltage.

 

Key electrical specifications include a maximum input voltage of 40V and a minimum input voltage of 4.2V. The output current capability is up to 1.5A, with an adjustable output voltage from 1.25V to 37V. It offers a typical dropout voltage of 1200mV and a typical quiescent current of 5mA. The device features a noise level of 75 µVrms and a PSRR of 40dB at 100 KHz.

 

This regulator operates within an ambient temperature range of -55°C to 125°C. It also provides features such as constant current limiting, output short-circuit protection, and 80dB ripple rejection. The LM117E is available in various package types including TO-CAN (NDT), TO-CAN (K), CFP (NAC), and LCCC (NAJ).

 

Designed for ease of use and superior performance compared to fixed regulators, the LM117E is suitable for a wide range of applications requiring adjustable positive voltage regulation.
