The LM2736XMK/NOPB is a Buck Switching Regulator IC manufactured by Texas Instruments with Positive Adjustable 1.25V 1 Output 750mA. It is a SOT-23-6 (Thin, TSOT-23-6) package and an ultra-small size that provides the convenience of surface mount technology. The LM2736XMK/NOPB is an efficient low-input voltage, 1A, step-down, switching regulator with adjustable output from 1.20V to 28V. It features an integrated, high-performance, voltage-mode PWM control that simplifies circuitry design while providing fast line and load transient response. In addition, the LM2736XMK/NOPB provides an improved efficiencies with ultra-low quiescent current over a wide input voltage range. Other features include programmable soft-start, short-circuit protection, output voltage up-and-down tracking, current-limit protection, and thermal overload protection. The LM2736XMK/NOPB is ideal for applications such as 5V to 1.2V step-down power solutions for many general purpose electronics, automotive, and industrial applications.
