Product details

Dropout and PSRR — the real margins

At 3 A the maximum dropout is 0.6 V. The PSRR runs 73 dB to 57 dB at 120 Hz.

Quiescent current and supply budget

The quiescent current is 10 mA typical, with a maximum supply current of 10 mA.

Package and mounting — thermal path

The DDPAK/TO-263-5 package has a large exposed tab on the bottom. For 3 A operation, the tab must be soldered to a copper plane.

Lifecycle and compliance

No last-time-buy or obsolescence notice is in effect. The part is marked RoHS non-compliant.

Frequently asked questions

Can LP3853ES-5.0 replace LP3853ES-ADJ?

No. The LP3853ES-5.0 has a fixed 5 V output; the ADJ variant uses an external resistor divider on the feedback pin. The pinout differs — they are not drop-in replacements.

What is the PSRR of LP3853ES-5.0?

PSRR is specified as 73 dB to 57 dB at 120 Hz. The rejection decreases at higher frequencies.

What package does LP3853ES-5.0 come in?

It ships in a DDPAK/TO-263-5 surface-mount package (5 leads plus tab), also described as TO-263-6, D²Pak.
