10 Power Supply Recommendations

The LPV821 is specified for operation from 1.7 V to 3.6 (±0.85 V to ±1.8 V); many specifications apply from –40°C to 125°C. The Typical Characteristics presents parameters that can exhibit significant variance with regard to operating voltage or temperature.

CAUTION

Supply voltages larger than 4 V can permanently damage the device (see the Absolute Maximum Ratings).

TI recommends placing 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high-impedance power supplies. For more detailed information on bypass capacitor placement, refer to the Layout section.
