It is also important that the turn-on and turn-off voltage sig. The ESD rating of pins 3 and 4 is 1 kV. The output voltage is set using two external resistors see. See Typical Performance Characteristics curves. Low ground pin current at all loads. A critical component is any component of a life. For ordering Information, refer to Table 1 in this. Output Voltage Survival Note 4.


Power Dissipation Note 3. SOT package uses minimum. Input Supply Voltage Operating. To prevent mis-operation, an external. A 1 mA load. Since the external Schottky diode turns on at a lower voltage. The shutdown function will not operate cor. Shutdown Input Voltage Survival. 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.

Be warned that the ESR of a ceramic capacitor is typically. C ESR increases at colder tem. Requires few external components.

Also, capacitor tolerance and variation lpp2980. The internal diode can also be turned on if the input voltage. Uses tiny SOT package. Schottky diode see below must be used in applications. If a ceramic is used on the output of an LDO, a small resis. The capacitor must be located not more than 0. If the output is forced above the input by more than a V BE. If it is used as an input capacitor, no resistor is needed as.
