LP2980IM5X-1.5 National Semiconductor, LP2980IM5X-1.5 Datasheet - Page 5

• Manufacturer Part Number: LP2980IM5X-1.5
• Description: Micropower SOT, 50 mA Low-Voltage Low-Dropout Regulator For Applications With Output Voltages < 2V
• Manufacturer: National Semiconductor

Electrical Characteristics
(Continued)
The value of θ
for the SOT-23 package is 220˚C/W. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator
JA
will go into thermal shutdown.
Note 4: If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2980LV output must be diode-clamped to ground.
Note 5: The output PNP structure contains a diode between the V
and V
terminals that is normally reverse-biased. Reversing the polarity from V
to V
IN
OUT
IN
OUT
will turn on this diode and possibly damage the device (see Application Hints).
Note 6: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 7: The ON/OFF input must be properly driven to prevent misoperation. For details, refer to Application Hints.
Note 8: See Typical Performance Characteristics curves.
