Component

load switch3 A1 V to 5.5 V25 mOhmUQFNno QOD

TPS22991BNRAAR is a compact 3 A load switch for 1 V to 5.5 V rails, with low on-resistance and a fast controlled output ramp. This BN variant does not discharge VOUT when disabled.

Best for

  • Compact power-rail switching
  • Battery-powered equipment
  • Rails needing a controlled fast turn-on

Avoid if

  • A defined VOUT discharge path is required when disabled
  • The load or startup inrush exceeds the device current and thermal limits

Check before use

  • Verify the OFF-state requirement because this BN version has no quick output discharge.
  • Use local VIN capacitance and keep CIN greater than CL as recommended.
  • Validate voltage drop and heating at the worst-case on-resistance.
