V2 TRACKING VOLTAGE REGULATOR - V2 specification with external capacitor

- option 1: C

≥ 22 µF and ESR < 10 ohm. Using a resistor of 2 kohm or less between the base and emitter of the external PNP is

recommended.

- option2: 1.0

µF < C < 22 µF and ESR < 10 ohm. In this case depending on the ballast transistor gain an additional resistor and

capacitor network between emitter and base of PNP ballast transistor might be required. Refer to Freescale application information

or contact your local technical support.

- option 3: 10uF < C < 22uF ESR > 0.2 ohms: a resistor of 2 kohm or less is required between the base and emitter of the external PNP.

Table 4. Static Electrical Characteristics (continued).

Characteristics noted under conditions - VSUP From 5.5 V to 18 V and TJ from -40°C to 125°C, unless otherwise noted. Typical

values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.
