NOTES: 3. The external PNP power transistor satisfies the following minimum specifications:
hFE ≥ 60 at IC = 500 mA and VCE = 5.0 V;
VCE(sat) ≤ 300 mV at IB = 10 mA and IC = 300 mA
4. Regulator Vout2 programmed for nominal 24 V output by means of R4, R5 (see Figure 1).
5. Tlow = 0°C for TCA5600
Tlow = –40°C for TCF5600
Thigh = +125°C for TCA5600 Thigh = +150°C for TCF5600
6. Pulse tested tp ≤ 300 µs.
