7.3 Recommended Operating Conditions

Over the recommended operating junction temperature range of –40°C to 150°C (unless otherwise noted)
MIN NOM MAX UNIT
Input voltage range after startup(1) 3.8 36 V
Output voltage range 5 V(2) 0 5.5 V
3.3 V(2) 0 3.63
Output adjustment range(3)for LM53600-Q1-ADJ (2), LM53601-Q1-ADJ(2) 3.3 6 V
Load current range LM53600-Q1 0 650 mA
LM53601-Q1 0 1000
Operating junction temperature(4) –40 150 °C
(1) An extended input voltage range to 3.55 V is possible; see Section 7.6. See input UVLO in Section 7.5 for startup conditions.
(2) Output voltage should not be allowed to fall below 0 V during normal operation.
(3) The LM53600-Q1 and LM53601-Q1 devices can operate outside of the listed range output voltage range. For output voltage outside of the listed range, contact Texas Instruments concerning alternate application circuit BOM and additional operational limitations such as higher IQ.
(4) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.
