STMicroelectronics A5972D
The A5972D is a step-down monolithic power switching regulator with a minimum switch current limit of 1.8 A so it is able to deliver up to 1.5 A DC current to the load depending on the application conditions. The output voltage can be set from 1.235 V to VIN. The device uses an internal P-channel DMOS transistor (with a typical RDS(on) of 250 mΩ) as a switching element to minimize the size of the external components.| Part No. | A5972D |

APPLICATIONS
● Dedicated to automotive applicationsDESCRIPTION
SO-8FEATURES
● Qualified following the AEC-Q100 requirements (see PPAP for more details)● 1.5 A DC output current
● Operating input voltage from 4 V to 36 V
● 3.3 V / (± 2%) reference voltage
● Output voltage adjustable from 1.235 V to VIN
● Low dropout operation: 100% duty cycle
● 250 kHz internally fixed frequency
● Voltage feedforward
● Zero load current operation
● Internal current limiting
● Inhibit for zero current consumption An internal oscillator fixes the switching frequency at 250 kHz. Having a minimum input voltage of 4 V only it fits the automotive applications requiring the device operation even in cold crank conditions. A pulse-by-pulse current limit with the internal frequency modulation offers an effective constant current short-circuit protection.
● Protection against feedback disconnection
