notes: 1. load regulation is speci ed for an output load change of 10% to 100%. 2. operation under 10% load will not damage the unit. however, it may not meet all speci cations. 3. measured at an internal ic junction. 4. quiescent current is speci ed at 0% load for v in = nom. 5. this regulator is not designed to be used in parallel with another unit to increase output power. 6. the input should not exceed the range given in the model selection chart. exceeding this limit could damage the unit. for right-angle pin option, add suf? x ?l? to model number (i.e. sru7805-15wl) model selection guide model number input voltage range (vdc) output ef ciency (%, typ) voltage (vdc) current (ma, max) min vin max vin sru7805-03w(l) 9.00 - 72.0 3.3 500.0 82 75 sru7805-05w(l) 9.00 - 72.0 5.0 500.0 87 81 sru7805-06w(l) 9.00 - 72.0 6.5 500.0 91 84 sru7805-09w(l) 14.0 - 72.0 9.0 500.0 92 86 sru7805-12w(l) 17.0 - 72.0 12.0 500.0 93 89 sru7805-15w(l) 20.0 - 72.0 15.0 500.0 94 90 sru7805-24w(l) 36.0 - 72.0 24.0 500.0 95 91 mechanical dimensions pin 1 2 3 function +vin gnd +vout pin connection derating curve characteristic curves (ef ciency & ripple) ef ciency vs input voltage (full load) ripple vs load (v in = max) ef ciency vs load (vin = min) ripple vs load (v in = nom) ef ciency vs load (v in = nom) ripple vs load (v in = min) www.micropowerdirect.com micropower direct we power your success - for less! 292 page street ste d stoughton, ma 02072 ? tel: (781) 344-8226 ? fax: (781) 344-8481 ? e-mail: sales@micropowerdirect.com notes: all dimensions are typical in inches (mm) tolerance x.xx = ?.01 (?.25) ? pin 1 is marked by a ?ot or indentation on the side of the unit
