150 mA LDO Linear Voltage Regulator with Reset, Delay, Adjustable Reset and Early Warning

NCV4269
5.0 V Micropower 150 mA
LDO Linear Regulator with
DELAY, Adjustable RESET,
and Sense Output
The NCV4269 is a 5.0 V precision micropower voltage regulator
with an output current capability of 150 mA.
The output voltage is accurate within ±2.0% with a maximum
dropout voltage of 0.5 V at 100 mA. Low quiescent current is a feature
drawing only 240 mA with a 1.0 mA load. This part is ideal for any and
all battery operated microprocessor equipment.
Microprocessor control logic includes an active reset output RO
with delay and a SI/SO monitor which can be used to provide an early
warning signal to the microprocessor of a potential impending reset
signal. The use of the SI/SO monitor allows the microprocessor to
finish any signal processing before the reset shuts the microprocessor
down.
The active Reset circuit operates correctly at an output voltage as
low as 1.0 V. The Reset function is activated during the power up
sequence or during normal operation if the output voltage drops
outside the regulation limits.
The reset threshold voltage can be decreased by the connection of an
external resistor divider to the RADJ lead. The regulator is protected
against reverse battery, short circuit, and thermal overload conditions.
The device can withstand load dump transients making it suitable for
use in automotive environments. The device has also been optimized
for EMC conditions.

APPLICATION DESCRIPTION
OUTPUT REGULATOR
If the reset adjust option is not needed, the RADJ pin
should be connected to GND causing the reset threshold to
go to its default value (typically 4.65 V).
The output is controlled by a precision trimmed reference.
The PNP output has base drive quiescent current control for
regulation while the input voltage is low, preventing over
saturation. Current limit and voltage monitors complement
the regulator design to give safe operating signals to the
processor and control circuits.
RESET DELAY (D)
The reset delay circuit provides a delay (programmable by
capacitor CD) on the reset output lead RO. The delay lead D
provides charge current ID,C (typically 6.5 mA) to the
external delay capacitor CD during the following times:
1. During Powerup (once the regulation threshold has
been exceeded).
2. After a reset event has occurred and the device is
back in regulation. The delay capacitor is set to
discharge when the regulation (VRT, reset
threshold voltage) has been violated. When the
delay capacitor discharges to VLD, the reset signal
RO pulls low.
RESET OUTPUT (RO)
A reset signal, Reset Output, RO, (low voltage) is
generated as the IC powers up. After the output voltage VQ
increases above the reset threshold voltage VRT, the delay
timer D is started. When the voltage on the delay timer VD
passes VUD, the reset signal RO goes high. A discharge of
the delay timer VD is started when VQ drops and stays below
the reset threshold voltage VRT. When the voltage of the
delay timer VD drops below the lower threshold voltage VLD
the reset output voltage VRO is brought low to reset the
processor.
The reset output RO is an open collector NPN transistor
with an internal 20 kW pullup resistor connected to the
output Q, controlled by a low voltage detection circuit. The
circuit is functionally independent of the rest of the IC,
thereby guaranteeing that RO is valid for VQ as low as 1.0 V.
SETTING THE DELAY TIME
The delay time is set by the delay capacitor CD and the
charge current ID. The time is measured by the delay
capacitor voltage charging from the low level of VDSAT to
the higher level VUD. The time delay follows the equation:
td + [CD (VUD * VD, SAT)]ńID, C
Example:
Using CD = 100 nF.
Use the typical value for VD,SAT = 0.1 V.
Use the typical value for VUD = 1.8 V.
Use the typical value for Delay Charge Current ID = 6.5 mA.
RESET ADJUST (RADJ)
The reset threshold VRT can be decreased from a typical
value of 4.65 V to as low as 3.5 V by using an external
voltage divider connected from the Q lead to the pin RADJ,
as shown in Figure 21. The resistor divider keeps the voltage
above the VRADJ,TH (typical 1.35 V) for the desired input
voltages, and overrides the internal threshold detector.
Adjust the voltage divider according to the following

instability. The aluminum electrolytic capacitor is the least
expensive solution, but, if the circuit operates at low
temperatures (−25°C to −40°C), both the value and ESR of
the capacitor will vary considerably. The capacitor
manufacturer’s data sheet usually provides this information.
The value for the output capacitor CQ shown in Figure 21
should work for most applications; however, it is not
necessarily the optimized solution. Stability is guaranteed at
values CQ = 10 mF and an ESR = 10 W within the operating
temperature range. Actual limits are shown in a graph in the
typical data section.
An on−chip comparator is available to provide early
warning to the microprocessor of a possible reset signal
(Figure 4). The output is from an open collector driver with
an internal 20 kW pull up resistor to output Q. The reset
signal typically turns the microprocessor off
instantaneously. This can cause unpredictable results with
the microprocessor. The signal received from the SO pin will
allow the microprocessor time to complete its present task
before shutting down. This function is performed by a
comparator referenced to the band gap voltage. The actual
trip point can be programmed externally using a resistor
divider to the input monitor SI (Figure 21). The values for
RSI1 and RSI2 are selected for a typical threshold of 1.20 V
on the SI Pin.
CALCULATING POWER DISSIPATION IN A SINGLE
OUTPUT LINEAR REGULATOR
The maximum power dissipation for a single output
regulator (Figure 21) is:
PD(max) + [VI(max) * VQ(min)] IQ(max) ) VI(max) Iq (eq. 4)
SIGNAL OUTPUT
where:
VI(max) is the maximum input voltage,
VQ(min) is the minimum output voltage,
IQ(max) is the maximum output current for the application,
and Iq is the quiescent current the regulator consumes at
IQ(max).
Once the value of PD(max) is known, the maximum
permissible value of RqJA can be calculated:
Figure 22 shows the SO Monitor timing waveforms as a
result of the circuit depicted in Figure 21. As the output
voltage (VQ) falls, the monitor threshold (VSI,Low), is
crossed. This causes the voltage on the SO output to go low
sending a warning signal to the microprocessor that a reset
signal may occur in a short period of time. TWARNING is the
time the microprocessor has to complete the function it is
currently working on and get ready for the reset
shutdown signal.
RqJA = (150°C – TA) / PD
(eq. 5)
The value of RqJA can then be compared with those in the
package section of the data sheet. Those packages with
RqJA’s less than the calculated value in equation 2 will keep
the die temperature below 150°C. In some cases, none of the
packages will be sufficient to dissipate the heat generated by
the IC, and an external heatsink will be required. The current

and
voltages

the
Measurement Circuit Diagram.

HEATSINKS
A heatsink effectively increases the surface area of the
package to improve the flow of heat away from the IC and
into the surrounding air.
Each material in the heat flow path between the IC and the
outside environment will have a thermal resistance. Like
series electrical resistances, these resistances are summed to
determine the value of RqJA:

RqJA + RqJC ) RqCS ) RqSA
(eq. 6)
where:
RqJC = the junction−to−case thermal resistance,
RqCS = the case−to−heat sink thermal resistance, and
RqSA = the heat sink−to−ambient thermal resistance.
RqJC appears in the package section of the data sheet. Like
RqJA, it too is a function of package type. RqCS and RqSA are
functions of the package type, heatsink and the interface
between them. These values appear in data sheets of
heatsink manufacturers. Thermal, mounting, and
heatsinking considerations are discussed in the
ON Semiconductor application note AN1040/D, available
on the ON Semiconductor website.
STABILITY CONSIDERATIONS
The input capacitor CI in Figure 21 is necessary for
compensating input line reactance. Possible oscillations caused
by input inductance and input capacitance can be damped by
using a resistor of approximately 1.0 W in series with CI.
The output or compensation capacitor helps determine
three main characteristics of a linear regulator: startup delay,
load transient response and loop stability.
The capacitor value and type should be based on cost,
availability, size and temperature constraints. A tantalum or
aluminum electrolytic capacitor is best, since a film or
ceramic capacitor with almost zero ESR can cause
