A 7 pF feed-forward ca. The temperature stability of Tantalums is typically very good.
Low ground pin current at all loads. Schottky diode see below must be used in applications.
LP2980 Datasheet PDF
Ceramics are generally larger and more costly. A 1 mA load.
This current must be. If used in a dual-supply system datssheet the regulator datasheett is returned to a negative supply, the LPADJ output must be diode-clamped to ground. Absolute maximum ratings indicate limits beyond which damage to the component may occur. The shutdown function will not operate cor. Input Supply Voltage Operating. Like any low-dropout regulator, the external capacitors must. Electrical specifications do not apply when operating the de.
Output Voltage Survival Note 4. Uses tiny SOT package. If the output is forced above the input by more than a V BE. Wide supply voltage range 2.
Kp2980 Voltage Note 7. For details, refer to Application Hints. The output capacitor must meet. It is recommended that the resis. Guaranteed 50 mA output current. It is also important that the turn-on and turn-off voltage sig.
Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control. An input capacitor whose value is. Power Dissipation Note 3. Ultra low dropout voltage. National does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and National reserves the right at any time without notice to change said circuitry and specifications.
Note that this capacitor must be located not more than 0. See Typical Performance Characteristics curves. A solid Tantalum capacitor is the best.

A quiescent current when shutdown. Input Supply Voltage Survival. The output voltage is set using two external resistors see.
Ground Pin Current vs. Also, capacitor tolerance and variation with. Off-brand capacitors should be avoided, as some poor qual.
Dropout voltage is defined as the input to output differential at which the output voltage drops mV below the value measured with a 1V differential. The ESR of a good quality Tantalum.
Since the external Schottky diode turns on at a lower voltage. F is required the amount of capacitance may be in. A critical component is any component of a life. The capacitor must be located not more than 0. A 50 mA load, and SOT package uses minimum. Distributors for availability and specifications.
Requires few external components. C, and limits in boldface type apply over the full operating temperature range.
