APPLICATION INFORMATION
Supply Voltage Transient
less than 8.0 V supply transients of more than 0.4 V/ms can
cause a reset signal perturbation. To improve the transient
behavior for supply voltages less than 8.0 V a capacitor at
Pin 3 can be used. A capacitor at Pin 3 (C3 ≤ 1.0 mF) also
reduces the output noise.
High supply voltage transients can cause a reset output
signal perturbation. For supply voltages greater than 8.0 V
the circuit shows a high immunity of the reset output against
supply transients of more than 100 V/ms. For supply voltages

OPERATING DESCRIPTION
The L4949 is a monolithic integrated low dropout voltage
regulator. Several outstanding features and auxiliary
functions are implemented to meet the requirements of
supplying microprocessor systems in automotive
applications. It is also suitable in other applications where
the included functions are required. The modular approach
of this device allows the use of other features and functions
independently when required.
Vout
Vout
5.0 V
Voltage Regulator
The voltage regulator uses an isolated collector vertical
PNP transistor as a regulating element. With this structure,
very low dropout voltage at currents up to 100 mA is
obtained. The dropout operation of the standby regulator is
maintained down to 3.0 V input supply voltage. The output
voltage is regulated up to a transient input supply voltage of
35 V.
A typical curve showing the standby output voltage as a
function of the input supply voltage is shown in Figure 16.
The current consumption of the device (quiescent current)
is less than 200 mA.
To reduce the quiescent current peak in the undervoltage
region and to improve the transient response in this region,
the dropout voltage is controlled. The quiescent current as
a function of the supply input voltage is shown in Figure 17.

Preregulator
To improve transient immunity a preregulator stabilizes
the internal supply voltage to 6.0 V. This internal voltage is
present at Pin 3 (VZ). This voltage should not be used as an
output because the output capability is very small (≤ 100
mA).
This output may be used to improve transient behavior for
supply voltages less than 8.0 V. In this case a capacitor (100
nF − 1.0 mF) must be connected between Pin 3 and GND. If
this feature is not used Pin 3 must be left open.

Reset Circuit
Output voltage drops below the reset threshold only
marginally longer than the reaction time results in a shorter
reset delay time.
The nominal reset delay time will be generated for output
voltage drops longer than approximately 50 ms. The typical
reset output waveforms are shown in Figure 19.
The block circuit diagram of the reset circuit is shown in
Figure 18.
The reset circuit supervises the output voltage. The reset
threshold of 4.5 V is defined by the internal reference
voltage and standby output divider.
The reset pulse delay time tRD, is defined by the charge
time of an external capacitor CT:
t
RD
+
Vout
C x 2.0 V
T

The reaction time of the reset circuit originates from the
discharge time limitation of the reset capacitor CT and is
proportional to the value of CT. The reaction time of the reset
circuit increases the noise immunity.

Sense Comparator
The sense comparator compares an input signal with an
internal voltage reference of typical 1.23 V. The use of an
external voltage divider makes this comparator very flexible
in the application.
It can be used to supervise the input voltage either before
or after a protection diode and to provide additional
information to the microprocessor such as low voltage
warnings.
