Application
The IC regulates an input voltage
voltage of
4.5 V). The reset delay can be set with an external capacitor. The device has two logic
inputs. A voltage of
Depending on the voltage on pin E6 the IC may be hold in active-state even if
to low level. This makes it simple to implement a self-holding circuit without external
components. When the device is turned off, the output voltage drops to 0 V and current
consumption tends towards 0 A.
Design Notes for External Components
The input capacitor
circuit consisting of lead inductance and input capacitance can be damped by a resistor
of approx. 1
regulating circuit. Stability is guaranteed at values of
the operating temperature range.
Circuit Description
The control amplifier compares a reference voltage, which is kept highly accurate by
resistance adjustment, to a voltage that is proportional to the output voltage and drives
the base of the series transistor via a buffer. Saturation control as a function of the load
current prevents any over-saturating of the power element.
The reset output RO is in high-state if the voltage on the delay capacitor
