LM9036

Ultra-Low Quiescent Current Voltage Regulator

General Description

The LM9036 ultra-low quiescent current regulator features

low dropout voltage and low current in the standby mode. With

less than 25µA Ground Pin current at a 0.1mA load, the

LM9036 is ideally suited for automotive and other battery op-

erated systems. The LM9036 retains all of the features that

are common to low dropout regulators including a low dropout

PNP pass device, short circuit protection, reverse battery pro-

tection, and thermal shutdown. The LM9036 has a 40V max-

imum operating voltage limit, a −40°C to +125°C operating

temperature range, and ±5% output voltage tolerance over

the entire output current, input voltage, and temperature

range.

Features

■Ultra low Ground Pin current (IGND ≤ 25µA for IOUT

= 0.1mA)

■Fixed 5V, 3.3V, 50mA output

■Output tolerance ±5% over line, load, and temperature

■Dropout voltage typically 200mV @ IOUT = 50mA

■−45V reverse transient protection

■Internal short circuit current limit

■Internal thermal shutdown protection

■40V operating voltage limit

Typical Application

20001101

* Required if regulator is located more than 2″ from power supply filter capacitor.

** Required for stability. Must be rated over intended operating temperature range. Effective series resistance (ESR) is critical, see Electrical Characteristics.

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, 100pF discharge through a 1.5kΩ 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 LM9036 will go into thermal shutdown.

Note 4: Typicals are at 25°C (unless otherwise specified) and represent the most likely parametric norm.

Note 5: Tested limits are guaranteed to National's AOQL (Average Outgoing Quality Level) and 100% tested.

Note 6: To ensure constant junction temperature, pulse testing is used.

Applications Information

Unlike other PNP low dropout regulators, the LM9036 re-

mains fully operational to 40V. Owing to power dissipation

characteristics of the package, 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.

On the TO-252 package the ground tab is thermally connect-

ed to the backside of the die. Adding 1 square inch of 2 oz.

copper pad area directly under the ground tab will improve the

θJA rating to approximately 50°C/W.

While the LM9036 has an internally set thermal shutdown

point of typically 150°C, this is intended as a safety feature

only. Continuous operation near the thermal shutdown tem-

perature should be avoided as it may have a negative affect

on the life of the device.

Using the θJA for a LM9036DT mounted on a circuit board as

defined at (Note 8), and using the formula for maximum al-

lowable dissipation given in (Note 3) for an ambient temper-

ature (TA) of +85°C, we find that PDMAX = 1.3W. Including the

small contribution of the quiescent current IQ to the total power

dissipation, the maximum input voltage (while still delivering

50mA output current) is 29.5V. The LM9036DT will go into

thermal shutdown when attempting to deliver the full output

current of 50mA, with an ambient temperature of +85°C, and

the input voltage is greater than 29.5V. Similarly, with an am-

bient temperature of 25°C the PDMAX = 2.5W, and the

LM9036DT can deliver the full output current of 50mA with an

input voltage of up to 40V.

While the LM9036 maintains regulation to 55V, it will not with-

stand a short circuit above 40V because of safe operating

area limitations in the internal PNP pass device. Above 55V

the LM9036 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 55V.
