RS3236-1.8YF5

RS3236 Low Power, Low Dropout, 500mA RF Linear Regulators FEATURES DESCRIPTION  Low Dropout Voltage • Cellular Telephones • Camera Modules • Modems The RS3236 series low-power, low-dropout, CMOS LDO operate from 1.7V to 7.5V input voltage that can supply up to 500 mA of output current. Designed to meet the requirements of RF and analog circuits, the RS3236 series device provides low noise, high PSRR, low quiescent current, and low line and load transient response. The device is designed to work with a 1-µF input and a 1-µF output ceramic capacitor (no separate noise bypass capacitor required). An external noise bypass capacitor connected to the device’s BP pin can further reduce the noise level. Other features include a 10nA logic-controlled shutdown mode, foldback current limit and thermal shutdown protection. The RS3236 series is available in Green UTDFN- • HiFi Audio Radio Transceivers 1x1-4, SOT23-5 ， SOT353(SC70-5) package. It • PLL/Synthesizer, Clocking • Medium-Current, Noise-Sensitive Applications operates over an ambient temperature range of 40°C to +85°C.  Thermal-Overload Protection  Output Current Limit  10nA Logic-Controlled Shutdown  20μA Low Supply Current  1.7V to 7.5V Input Voltage Range  500mA Output Current  -40°C to +85°C Operating Temperature Range  Available in Green UTDFN-1x1-4, SOT23-5， SOT353(SC70-5) Package APPLICATIONS Functional Block Diagram Current Limit IN 1.2V VREF OUT Error amp Internal Controller Thermal Shutdown EN BP GND REV A.3 1 Copyright © 2017, RUNIC Technology www.run-ic.com RS3236 Pin Configuration and Functions (Top View) (TOP VIEW) (TOP VIEW) IN 1 5 OUT GND 2 EN UTDFN-1×1-4 3 4 BP SOT23-5/SOT353(SC70-5) UTDFN-1×1-4 DESCRIPTION I/O NUMBER NAME 1 OUT O Regulator Output. 2 GND G Ground. 3 EN I Enable Input.
