4 / 11 page TPS79718 TPS79730 TPS79733 SLVS332B – MARCH 2001 – REVISED JUNE 2001 4 www.ti.com functional block diagram _ + Delay VIN Current Sense R1 R2 VIN GND VOUT PG ILIM Bandgap Reference Vref = 1.235 V Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION GND 2 Ground NC 3 No connection OUT 5 O The OUT terminal provides the regulated output voltage of the device. PG 1 O The PG terminal for the fixed voltage option devices is an open drain, active-high output that indicates the status of VO (output of the LDO). When VO exceeds approximately 90% of the regulated voltage, PG goes to a high impedance state. It goes to a low-impedance state when VO falls below approximately 90% (i.e. overload condition) of the regulated voltage. The open drain output of the PG terminal requires a pullup resistor. IN 4 I The IN terminal is the power supply input to the device. |
