TI1 LM2936QHBMAX-5.0 Ultra-low quiescent current ldo voltage regulator Datasheet

LM2936Q
Ultra-Low Quiescent Current LDO Voltage Regulator
General Description
Features
The LM2936Q ultra-low quiescent current regulator features
low dropout voltage and low current in the standby mode. With
less than 15 μA quiescent current at a 100 μA load, the
LM2936Q is ideally suited for automotive and other battery
operated systems. The LM2936Q retains all of the features
that are common to low dropout regulators including a low
dropout PNP pass device, short circuit protection, reverse
battery protection, and thermal shutdown. The LM2936Q has
a 40V maximum operating voltage limit, a −40°C to +125°C
operating temperature range, and ±3% output voltage tolerance over the entire output current, input voltage, and temperature range. The LM2936Q is available in a SO-8
package, SOT-223 surface mount package and TO-252 surface mount package.

* Required if regulator is located more than 2″ from power supply filter capacitor.
** Required for stability. See Electrical Characteristics for required values. Must be rated over intended operating temperature range. Effective series resistance (ESR) is critical, see curve. Locate capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without
bound.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified operating ratings.
Note 2: Human body model, 100 pF discharge through a 1.5 kΩ resistor.
Note 3: The maximum power dissipation is a function of TJmax, θJA, and TA. The maximum allowable power dissipation at any ambient temperature is
PD = (TJmax − TA)/θJA. If this dissipation is exceeded, the die temperature will rise above 150°C and the LM2936Q will go into thermal shutdown.
Note 4: Typicals are at 25°C (unless otherwise specified) and represent the most likely parametric norm.
Note 5: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 6: To ensure constant junction temperature, pulse testing is used.

Unlike other PNP low dropout regulators, the LM2936Q remains fully operational to 40V. Owing to power dissipation
characteristics of the available packages, full output current
cannot be guaranteed for all combinations of ambient temperature and input voltage.
The junction to ambient thermal resistance θJA rating has two
distinct components: the junction to case thermal resistance
rating θJC; and the case to ambient thermal resistance rating
θCA. The relationship is defined as: θJA = θJC + θCA.
For the SO-8 and TO-252 surface mount packages the θJA
rating can be improved by using the copper mounting pads
on the printed circuit board as a thermal conductive path to
extract heat from the package.
On the SO-8 package the four ground pins are thermally connected to the backside of the die. Adding approximately 0.04
square inches of 2 oz. copper pad area to these four pins will
improve the θJA rating to approximately 110°C/W. If this extra
pad are is placed directly beneath the package there should
not be any impact on board density.
On the TO-252 package the ground tab is thermally connected to the backside of the die. Adding 1 square inch of 2 oz.
Shutdown Pin
The LM2936QHBMA–5.0 has a pin for shutting down the regulator output. Applying a Logic Level High (>2.0V) to the
Shutdown pin will cause the output to turn off. Leaving the
Shutdown pin open, connecting it to Ground, or applying a
Logic Level Low (<0.6V) will allow the regulator output to turn
on.
11
www.ti.com
LM2936Q
copper pad area directly under the ground tab will improve the
θJA rating to approximately 50°C/W.
While the LM2936Q has an internally set thermal shutdown
point of typically 160°C, this is intended as a safety feature
only. Continuous operation near the thermal shutdown temperature should be avoided as it may have a negative affect
on the life of the device.
While the LM2936Q maintains regulation to 60V, it will not
withstand a short circuit above 40V because of safe operating
area limitations in the internal PNP pass device. Above 60V
the LM2936EP will break down with catastrophic effects on
the regulator and possibly the load as well. Do not use this
device in a design where the input operating voltage may exceed 40V, or where transients are likely to exceed 60V.
