DESCRIPTION

 

The LP2980-N is a 50 mA, fixed-output voltage

regulator designed specifically to meet the requirements of battery-powered applications.

Using an optimized VIP (Vertically Integrated PNP  process, the LP2980-N delivers unequaled

performance in all specifications critical to battery powered designs:

 

Dropout Voltage. Typically 120 mV @ 50 mA load, and 7 mV @ 1 mA load.

 

Ground Pin Current. Typically 375 μA @ 50 mA load, and 80 μA @ 1 mA load.

 

 

Sleep Mode. Less than 1 μA quiescent current when ON/OFF pin is pulled low.

 

Minimum Part Count. Requires only 1 μF of external capacitance on the regulator output.

 

Precision Output. 0.5% tolerance output voltages available (A grade).

5.0V, 4.7V, 3.3V, 3.0V and 2.5V versions available as standard products.

Storage Temperature Range −65°C to +150°C
Operating Junction Temperature Range −40°C to +125°C
Lead Temperature (Soldering, 5 sec.) 260°C
ESD Rating(3) 2 kV
Power Dissipation(4) Internally Limited
Input Supply Voltage (Survival) −0.3V to +16V
Input Supply Voltage (Operating) 2.1V to +16V
Shutdown Input Voltage (Survival) −0.3V to +16V
Output Voltage (Survival)(5) −0.3V to +9V
IOUT (Survival) Short Circuit Protected
Input-Output Voltage (Survival)(6) −0.3V to +16V

 

(1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside of its rated operating conditions. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) The ESD rating of pins 3 and 4 for the SOT-23 package is 1 kV. (4) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: The value of θJA for the SOT-23 package is 220°C/W. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. (5) If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2980-N output must be diode-clamped to ground. (6) The output PNP structure contains a diode between the VIN and VOUT terminals that is normally reverse-biased. Reversing the polarity from VIN to VOUT will turn on this diode (See REVERSE CURRENT PATH).

 

 

ELECTRICAL CHARACTERISTICS

Limits in standard typeface are for TJ = 25°C, and limits in boldface type apply over the full operating temperature range. Unless otherwise specified: VIN = VO(NOM) + 1V, IL = 1 mA, COUT = 1 μF, VON/OFF = 2V
