Guaranteed 50 mA output current. C Junction temperature range. Dropout Voltage Note 7.

One caution about Tantalums if they are used on the input: The ESD rating of pins ddatasheet and 4 is 1 kV. The ESR of a good quality Tantalum. It is also important that the turn-on and turn-off voltage sig. To ensure proper operation, the signal source used to drive. Output Voltage Survival Note 4.


Since the external Schottky diode turns on at a lower voltage. See Typical Performance Characteristics curves.

It is recommended that the resis. The maximum allowable power dissipation at any ambient temperature is calculated using: Low ground pin current at all loads. Also, capacitor tolerance and variation with. If the output is forced above the input by more than a V BE.

High peak current capability mA typical. Absolute Maximum Ratings Note 1. Note that this capacitor must be located not more than 0. Uses tiny SOT package.

Off-brand capacitors should be avoided, as some poor qual. For ordering Information, refer to Table 1 in this. Wide supply voltage range 2.

Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control.

A solid Tantalum capacitor is the best.

TC – Linear Regulators – Power Management

Equivalent Series Resistance for stable opera. ESD Rating Note 2. Package Marking and Ordering Information.

Any good quality Tantalum or Ceramic capacitor may be. Input Supply Voltage Operating. A 1 mA load. If it is used as an input capacitor, no resistor is needed as. F is required the amount of capacitance may be in.


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. Ultra low dropout voltage.

Life support devices or systems are devices daatsheet. For details, refer to Application Hints. SOT package uses minimum.

The output capacitor must maintain its ESR in. Like any low-dropout regulator, the external capacitors must. Output adjusts from 1.
