With a typical IQ of only 1.2\u03bcA, it is specifically designed for battery-powered applications where long standby times are critical. The device supports input voltages up to 24V and provides up to 50mA output current with an adjustable output voltage set by an external resistor divider. The wide input range, ultra-low IQ, and tiny SC-70 package make it an excellent choice for always-on power rails in IoT, industrial, and automotive systems.","working_principle":"The TPS71501 uses a PMOS pass transistor controlled by an error amplifier that compares a fraction of the output voltage (via the FB pin and external resistor divider) with an internal bandgap reference voltage. The extremely low quiescent current is achieved by operating the error amplifier and bandgap reference at very low bias currents. A bypass capacitor on the NR\/FB pin can further reduce output noise. When the output current exceeds the limit threshold, the internal current limit circuit reduces the gate drive to the pass transistor, protecting the device. Thermal shutdown activates when junction temperature exceeds the threshold, turning off the pass transistor until the temperature drops.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>IN<\/td><td>Power<\/td><td>Input supply voltage (2.5V-24V)<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr><tr><td>3<\/td><td>EN<\/td><td>Input<\/td><td>Enable \u2014 high enables the device<\/td><\/tr><tr><td>4<\/td><td>FB<\/td><td>Input<\/td><td>Feedback \u2014 connect resistor divider from output<\/td><\/tr><tr><td>5<\/td><td>OUT<\/td><td>Power<\/td><td>Regulated output voltage<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Always-on power rail for IoT sensor nodes with 10+ year battery life<\/li><li>Low-dropout regulation in 4-20mA loop-powered instruments<\/li><li>Post-regulation stage after switching converter for noise-sensitive circuits<\/li><li>Portable medical device standby power supply<\/li><li>Automotive body control module always-on rail<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>TPS71525DCKR<\/td><td>SC-70-5<\/td><td>Fixed 2.5V output version<\/td><\/tr><tr><td>TI<\/td><td>TPS71533DCKR<\/td><td>SC-70-5<\/td><td>Fixed 3.3V output version<\/td><\/tr><tr><td>Microchip<\/td><td>MCP1811T<\/td><td>SOT-23-5<\/td><td>Low IQ LDO, 350nA IQ<\/td><\/tr><tr><td>Maxim<\/td><td>MAX8873<\/td><td>SOT-23-5<\/td><td>Low IQ LDO, 3.2\u03bcA<\/td><\/tr><tr><td>Richtek<\/td><td>RT9013<\/td><td>SOT-23-5<\/td><td>Low IQ LDO, similar spec<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10643","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/comments?post=10643"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10643\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/media?parent=10643"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/categories?post=10643"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/tags?post=10643"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=10643"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
