LP5990TM-1.8EV
| LP5990TM-1.8 Evaluation Board | Full production
|
| $55.00 each | 1 |
| Description:
The LP5990 regulator is designed to meet the requirements of portable, battery-powered systems providing an accurate output voltage, low noise and low quiescent current.
The LP5990 will provide a 1.8V output from a low input voltage of 2.2V and can provide 200mA to an external load. When switched into shutdown mode via a logic signal at the enable pin, the power consumption is reduced to virtually zero.
Fast shut down is achieved by the push pull architecture.
This evaluation board is designed to allow the evaluation of the LP5990 Low Voltage CMOS Regulator. Each board is pre-assembled and tested in the factory. The board contains the LP5990 in a 4 bump micro SMD, 0.4mm pitch package with input and output capacitors connected to GND. The LP5990 will provide a 1.8V regulated output from a low input voltage of 2.2V and can provide 200mA to an external load. The LP5990 is particularly suitable for powering digital circuits, where good transient behavior is required.
The LP5990 is designed to be stable with space saving 0402 capacitors as small as 1µF.
Features:
- Operation from 2.2V to 5.5V input
- ±1% accuracy over temp range
- Output voltage from 0.8V to 3.6V in 50mV increments
- 30µA Quiescent current (enabled)
- 10nA Quiescent current (disabled)
- 160mV dropout at 200mA load
- 60µV RMS Output voltage noise
- 60 µs start-up time
- 500 µs shut-down time
- PSRR 55 dB at 10kHz
- Stable with 0402 1.0 µF ceramic capacitors
- Logic controlled enable
- Thermal-overload and short-circuit protection
Applications:
- Cellular phones
- Hand-held information appliances
- David Chin already has the assembled boards
