Output Voltage Survival Note 4. Input Supply Voltage Survival.

Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator. SOT package uses minimum. An input capacitor whose value is. Also, capacitor tolerance and variation with. Like any low-dropout regulator, the external capacitors must. The ESD rating of pins 3 and 4 is 1 kV. Absolute maximum ratings indicate limits beyond which damage to the component may occur.


Input Supply Voltage Operating. If the output is forced above the input datasheft more than a V BE. A 1 mA load. The temperature stability of Tantalums is typically very good. The output voltage is set using two external resistors see. Absolute Maximum Ratings Note 1.

Curves are provided below which show the allowable ESR of. A solid Tantalum capacitor is the best. The output capacitor must meet.

C ESR increases at colder tem. A critical component is any component of a life. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control. Since the external Schottky diode turns on at a lower 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. Output adjusts from 1.

The ESR of a good quality Tantalum. Note that this capacitor must be located not more than 0. ESD Rating Note 2.

Shutdown Input Voltage Survival. Schottky diode see below must be used in applications. Be warned that the ESR of a ceramic capacitor is typically. If it is used as an input capacitor, no resistor is needed as.

F is required the amount of capacitance may be in.

LP2980 Datasheet PDF

The maximum allowable power dissipation at any ambient temperature is calculated using: The capacitor must be located not more than 0. Equivalent Series Resistance for stable opera.

The internal diode can also be turned on if the input voltage. Dropout Voltage Note 7. A quiescent current when shutdown. The output capacitor must maintain its ESR in. Requires few external components. C Junction temperature range. Ground Pin Current vs. If a ceramic is used on the output of an LDO, a small resis. The shutdown function will not operate pp2980.
