If a ceramic is used on the output of an LDO, a small resis. If the output is forced above the input by more than a V BE. The ESD rating of pins 3 and 4 is 1 kV.
For details, refer to Application Hints. The capacitor must be located not more than 0. The temperature stability of Tantalums is typically very good. 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. Absolute Maximum Ratings Note 1. A 7 pF feed-forward ca. Ground Pin Current vs.
Wide supply voltage range 2.
Input Supply Voltage Survival. C Junction temperature range. A 1 mA load. If used in a dual-supply system where the regulator load is returned to a negative supply, the LPADJ output must be diode-clamped to ground. The internal diode can also be turned on if the input voltage.
It is also important that the turn-on and turn-off voltage sig. A quiescent current when shutdown.
This current must be. ESD Rating Note 2. Life support devices or systems are devices or.
Dropout Voltage Note 7. A 50 mA load, and Uses tiny SOT package. The ESR of a good quality Tantalum. Like any low-dropout regulator, the external capacitors must. Any good quality Tantalum or Ceramic capacitor may be. High peak current capability mA typical. See Typical Performance Characteristics curves.
One caution about Tantalums if they are used on the input: Requires few external components. The output capacitor must meet. Input Supply Voltage Operating. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control. C ESR increases at colder tem. Output Voltage Survival Note 4.
Off-brand capacitors should be avoided, as some poor qual. Absolute maximum ratings indicate limits beyond which lp22980 to the component may occur.
TC – Linear Regulators – Power Management
An input capacitor whose value is. The output capacitor must maintain its ESR in. Low ground pin current at all loads.
Schottky diode see below must be used in applications. Guaranteed 50 mA output current.

The maximum allowable power dissipation at any ambient temperature is calculated using: Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator. A critical component is any component of a life. Be warned that the ESR of a ceramic capacitor is typically. It is recommended that the resis. Package Marking and Ordering Information. The output voltage is set using two external resistors see.
For ordering Information, refer to Table 1 in this. Output adjusts from 1. Shutdown Input Voltage Survival. Electrical specifications do not apply when operating the de. Ultra low dropout voltage.
