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.

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.
