TPS65320DQPWPRQ1 Information

TPS65320D-Q1 Automotive LDO Regulators

Texas Instruments TPS65320D-Q1 Automotive LDO Regulators combine a high-VIN DC-DC step-down converter and a high-VIN 280mA low-dropout (LDO) regulator, providing a flexible design to fit system needs. The buck regulator offers an adjustable switch-mode frequency from 100kHz to 2.5MHz, while the low-dropout (LDO) regulator provides a high-VIN 280mA current capability with typical 35µA quiescent current in a No-Load Condition. The buck regulator has an integrated 250mΩ high-side MOSFET and an input range of 3.6V to 36V. The LDO regulator features a low-input supply current of 45µA typical in no-load and additionally provides an integrated MOSFET with an active-low, push-pull reset output pin. The low-ripple pulse-skip mode reduces the no-load input-supply current to a maximum of 140µA. Built-in protection features include soft start, current-limit, thermal sensing and shut down due to excessive power dissipation. The TPS65320D-Q1 devices are AEC-Q100 qualified for automotive applications.
