Product overview

Description

The LDL212 provides 1.2 A of maximum current from an input voltage range from 2.5 V to 18 V, with a typical dropout voltage of 350 mV @ 1.2 A. The high power supply rejection ratio of 87 dB at 120 Hz, and more than 40 dB at 100 kHz, makes the LDL212 suitable for direct regulation in SMPS and secondary linear regulation in DC-DC converters. The LDL212 goes to shutdown mode due to the enable logic control function, reducing the total current consumption.
The device also includes the current limit, SOA and thermal protections.
  • All features

    • Input voltage from 2.5 V to 18 V
    • 20 V AMR
    • Any fixed output voltages, from 1.2 V to 12 V in 100 mV steps (from 1.2 V to 6.6 V in 50 mV steps) available on request
    • Adjustable version from 1.18 V to VIN - VDROP(MAX)
    • Guaranteed output current 1.2 A
    • Typical dropout 350 mV @ 1.2 A
    • Undervoltage lockout
    • Enable function
    • Internal thermal, current and power limitation
    • High PSRR: 87 dB @ 120 Hz, 75 dB @ 1 kHz
    • Operating temperature range: -40 °C to 125 °C
    • Packages SO-8 batwing plastic micropackage, DFN6 (3x3) and DFN6 (2x2)
