LM117 Electrical Characteristics

(1) (continued)

Specifications with standard type face are for TJ = 25°C, and those with boldface type apply over full Operating

Temperature Range. Unless otherwise specified, VIN − VOUT = 5V, and IOUT = 10 mA.

(1)

IMAX = 1.5A for the NDS (TO-3), NDE (TO-220), and KTT (TO-263) packages. IMAX = 1.0A for the DCY (SOT-223) package. IMAX = 0.5A

for the NDT (TO), MDT (PFM), and NAJ (LCCC) packages. Device power dissipation (PD) is limited by ambient temperature (TA), device

maximum junction temperature (TJ), and package thermal resistance (θJA). The maximum allowable power dissipation at any

temperature is : PD(MAX) = ((TJ(MAX) - TA)/θJA). All Min. and Max. limits are ensured to TI's Average Outgoing Quality Level (AOQL).

(2)

Regulation is measured at a constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to

heating effects are covered under the specifications for thermal regulation.
