Electrical Characteristics
LM4132-4.1 (V
OUT = 4.096V)
Limits in standard type are for T
J = 25C only, and limits in boldface type ap-
ply over the junction temperature (T
J) range of -40C to +125C unless otherwise specified. Minimum and Maximum limits are
guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric norm at T
J =
25C, and are provided for reference purposes only. Unless otherwise specified V
IN = 5V and ILOAD =0

Note 1: Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications, see Electrical Characteristics.
Note 2: Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by TJMAX (maximum
junction temperature),
θJ-A (junction to ambient thermal resistance) and TA (ambient temperature). The maximum power dissipation at any temperature is: PDissMAX
=(TJMAX -TA)/θJ-A up to the value listed in the Absolute Maximum Ratings. θJ-A for SOT23-5 package is 220C/W, TJMAX = 125C.
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin.
Note 4: Limits are 100% production tested at 25C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control.
Note 5: Typical numbers are at 25C and represent the most likely parametric norm.
Note 6: Temperature coefficient is measured by the "Box" method; i.e., the maximum
VREF is divided by the maximum T.
Note 7: Long term stability is VREF @25C measured during 1000 hrs.
Note 8: Thermal hysteresis is defined as the change in +25C output voltage before and after cycling the device from (-40C to 125C).
Note 9: Dropout voltage is defined as the minimum input to output differential at which the output voltage drops by 0.5% below the value measured with a 5V input.
