LD3985M12R
LD3985M12R - Brand New STMicroelectronics IC Chips
- One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
DESCRIPTION
The LD3985 provides up to 150mA, from 2.5V to 6V input voltage. The ultra low drop-voltage, low quiescent current and low noise make it suitable for low power applications and in battery powered systems. Regulator ground current increases only slightly in dropout, further prolonging the battery life. Power supply rejection is better than 60 dB at low frequencies and starts to roll off at 10KHz. High power supply rejection is maintained down to low input voltage levels common to battery operated circuits.
