Texas Instruments launches new low-dropout (LDO) linear regulator. The TLV740P is a low quiescent current LDO with excellent line and load transient performance designed for power-sensitive applications. This device provides a typical accuracy of 1%.

The TLV740P also provides inrush current control during device power up and enabling. The TLV740P limits the input current to the defined current limit to avoid large currents from flowing from the input power source. This functionality is especially important in battery-operated devices.

The TLV740P is available in standard DQN and DBV packages. The TLV740P also provides an active pulldown circuit to quickly discharge output loads.

Features

  • Foldback overcurrent protection
  • Packages:
    • 1-mm × 1-mm, 4-pin X2SON (preview)
    • 5-pin SOT-23
  • Very low dropout: 460 mV at 300 mA
  • Accuracy: 1%
  • Low IQ: 50 μA
  • Input voltage range: 1.4 V to 5.5 V
  • Available in fixed-output voltages: 1 V to 3.3 V
  • High PSRR: 65 dB at 1 kHz
  • Active output discharge
