V2 TRACKING VOLTAGE REGULATOR - V2 specification with external capacitor
- option 1: C
22 F 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
F < C < 22 F 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: 10 uF < C < 22
F 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 to 125 °C, unless otherwise noted. Typical
values noted reflect the approximate parameter means at TA = 25 °C under nominal conditions unless otherwise noted.
