HIGH WITHSTAND-VOLTAGE VOLTAGE REGULATOR WITH RESET FUNCTION
S-87X Series
14
Seiko Instruments Inc.
Operation
1.
Reference Voltage Circuit
The reference voltage circuits operate all the time while voltage is applied
to V
IN
pin independently of V
PF
signal.
2.
Voltage Regulator
Figure 7 shows the voltage regulator circuit.
The S-87X Series has a Pch
MOS transistor as the output control transistor.
Reverse current may break IC if V
OUT
potential is higher than V
IN
,
because a parasitic diode is formed between V
IN
and V
OUT
due to the
structure of the control transistor. Therefore, keep V
OUT
lower than
V
IN
+0.3 V.
The output voltage of the voltage regulator can be selected as follows :
2.6V to 5.8V
±2.4% (0.1V step)
Note
For an application with a load current of less than 1
μ
A, the
leakage current of the control transistor M1 increases the output
voltage.
3.
Short-circuit Protection Circuit
The S-87X Series has a built-in short-circuit protection circuit to protect the element from break caused by a large current in
case of a short circuit. The output short current is internally limited to approx. 70 mA. Short-circuit protection circuit has
three kinds characteristics according to VIN (input voltage) as shown in Figure 8.
Note:
Use a voltage regulator under the specified power dissipation of
the package.
